Demars Jeffrey C. Evar Schlosser and M. Bastick History and Development Koerner Broms Broms Introduction New knowledge of tbe interaction between foundations and their environments, suchas erosion, subsidence, hazardous and toxic vases, and earthquakes has also been developed The second edition attempts 10 update the material in view of the developments cited above. It can also be used asa textbook in applied geotechnical engineering.

Thanks are also due to Ms. Eleanor [Nothelfer for her general aid in preparing the manuscript. Elias and Associates, P. Consulting Engineers Evans, Jeffrey C. Kulhawy, FredH. Philip F. Structures for which the basie problem is the interaction of the structure and the surrounding ground. Such structures, include foundations, retaining walls, bulkheads, tunnel linings, and buried pipes. Areal extent, depth, and thickness of each identifiable soil stratum, within a limited depth dependent on the size and nature of the structure, together with a description of the soil including its degree of density ifcohesionless and degree of stiffness if cohesive 2.

Depth to top of rock and the character ofthe rock, including such items as lithology; areal extent, depth, and thickness ofeach stratum: strike dip. Location of groundwater and the presence and magnitude of artesian pressures. Indirect methods include: aerial photography and topographic map interpretation, and the use of existing geological reports, maps, and soil surveys.

Direct methods comprise the following. Geologic field reconnaissance, including the examination of in situ materials in natural and man-made exposures such as river banks, escarpments, highway and railway cuts, quarries, and existing shafts and tunnels. Soundings and probings. Simple field tests, such as the Standard Penetration Test SPT and the static cone penetration test, whose results hhaye been correlated with engineering properties on a general basis, 5.

A list of references is given at the end of the chapter. At times, the explorations may be used to obtain information for the analysis of the failure of an engineering structure Explorations are normally accomplished ina phased sequence as follows: 1. Reconnaissance investigations 2. Explorations for preliminary design 3.

Explorations for detailed design 4. Foundation Engineering Handbook Each phase of explorations together with the engineering done in that phase discloses problems that require further investigation in the next phase. Not all phases are required on all projects; the fourth phase generally is not necessary. A general rule of thumb is that the cost of the subsurface explorations for design should be in the range of 05 to 1. The lower percentage is for large projects and for projects with lessecrtical subsurface conditions: the higher percentage is for smaller projects and for projects with critical subsurface conditions.

About half the cost would be expended for explorations for preliminary design and about half for detailed design. A very much smaller amount of money would be expended for explorations in the reconnaissance investigation phase.

No rule ofthumb canbe given forthe cost of explorations during construction. Such explorations are used to investigate special problems that may arise during construction orto better delineate the materialsin borrow areas or quattes in connection th the contractor's scheduling of his operations.

Generally they are not required but, when used, ther cost can vary widely from one project to another. In the case ofa lightweight structure that isto be founded in an area of relatively uniform subsurface conditions, this minimum rnumber of borings generally will sufice and all borings may be completed during a single exploration program. In such cases, the much-preferred procedure is to proceed with the engineering on the basis of the best assumptions that can be made from the available subsurface information, but to continue withthe full and proper program of explorations and testing.

The information obtained will then either confirm the assumptions made to complete the engineering on time or indicate where changes in the design assumptions have to be made. In such instances the sequence willbe governed by the ease of operation for the driller. Movement of the rigs between borings will be Kept to a minimum; all brings in one area of the site may be drilled before those in another area are started.

Often itis not only advantageous but essential thatthe engineer designate the sequence of the explorations. The sequence may also be dictated by time limitations ifthe time available for design is short. It is, not unusual for project design and laboratory testing to be concurrent with the explorations. The types of rigs used forexploration work and thir applicability to various conditions are discussed in a subsequent Section.

The minimum number of rigs required to perform an exploration program is dependent fn the time available forthe execution of the program, the rate Of advancement of the holes by the selected rigs, and the Sequence of explorations.

The estimated rate of advancement of the hole should include time allowances for equipment breakdowns, movement of the rigs from one location to another and standby due to weather. If only classification of the sol strata is required, disturbed samples will suffice and samplers such as the split-tube drive sampler may be used. If, on the other hand, the ultimate goal is the determination of the engineering properties of the soils by laboratory testing, more sophisticated equipment such as the thin-wall tube and double-tube core barrel samplers will 'be required.

The types of samplers available and the specific conditions under which each may be used are discussed in detail in the paragraphs on samplers and sampling techniques. This program, for a localized project such as a building that is to be constructed on a preselected site, will be somewhat limited in scope. However, when a dam or highway project is under consideration, several alternative sites or alignments must be considered. The information obtained in this phase aids in the selection of the alternative sites or alignments for investigation.

The types of information available from the USGS, as well as from other sourees, are discussed below. Topographic maps may also be used in much the same manner as aerial photographs. The maps donot have the detail ofaerial photographs and, therefore, limit the capabilites of the observer. However, in the complete absence of aerial photographs or as an initial step, the use of the maps is worthwhile.

Under proper conditions, itis possible to determine structural features such as dip and strike, folding, faulting, and relative consistency.

Each map covers a quadrangle area bounded by lines of latitude and longitude. Maps covering areas of 75 of latitude by 7. Hawaii is partially covered by series of maps at and Some shaded-reliet maps and metropolitan area maps are also published by the USGS.

Geological Survey and the supplements thereto that are published monthly. Maps of larger areas are plotted at seales of and The coastline charts, plotted at scales from to are useful for offshore work Other sources of topographic information for the United States include the US. Army Corps of Engineers, which publishes topographic maps and charts of some rivers and adjacent shores plus the Great Lakes and their connecting waterways: the USS.

Forest Service, which publishes forest reserve maps; and the Hydrographic Office of the Department of the Navy, which publishes nautical and aeronautical charts. Two excellent sources of general information are the American Geographic Society maps, which cover a large portion of South and Central America, and the British Admiralty charts, 1.

A color code is used to give the approximate scale of each map. A text on the sheet also gives the source of publication, sale, date, and author of each geologic map and 4 complete list of USGS reports on the state. Since , the folios have been replaced by individual quadrangle maps.

The first consists of those books, papers, etc, variously refered to as bulletins, cireulars, mineral resources publications, monographs, and professional papers that are detailed geologic studies of limited scope. The second category includes the water supply papers, which deal with various topics, among which are included detailed studies of surface and subsurface water flow in specific areas.

These papers often include detailed geologic descriptions and maps of the area under consideration. A list ofthe names and addresses of state geologists is contained in Hunt , Appendix B.

These surveys, which consist fof the mapping of surface and near-surface soils over a large expanse of land, are of two types, agricultural and engineering. Since both types usually cover an entire county, the information contained in them is, of necessity, generalized. This information, published in the form of text and maps, is particularly useful for projects such as highways.

The results fof the surveys are presented in the form of reports and maps that commonly, but not always, cover a complete county. The soil descriptions are done in accordance with the pedologic method. The earlier reports were directed entitely toward the use of the soils for agricultural purposes and the accuracy of the mapping varied significantly.

In spite of this, the information that was presented has been utilized successfully for engineering purposes by some state highway organizations that have correlated the observed behavior of pavements with the classifications as given in the USDA reports and maps.

In addition, in some states, engineering supplements to the agricultural survey reports hhave been prepared by local authorities. These supplements provide data on the drainage characteristics of the materials and anticipated engineering problems. Highway Research Board Bulletin R Committee on Surveying, Mapping, and Classification of Soils, contains a list of the soil survey reports published to the time of its printing and rates these surveys on the basis of the adequacy of the soil mapping performed.

A current list of published soil surveys may be obtained from the U'S. Department of Agriculture, Soil Conservation Service. The survey reports comprise a general volume and an individual volume for each county in the state, The general volume describes the climate, physiography, geology, and soils of the state, the mapping and soil-testing techniques used, and the symbolic notation used for the identification ofthe various soil types.

Included in the text are general data on the physiography, surface drainage, and geology of the area covered and detailed information concerning the major soil formations found in the area. This information includes the geologic identification and general characteristics of the parent formation; the nature of the underlying formations; the land form; the types of soils included under the general grouping: the engineering lassification of the material; the drainage characteristics: and a discussion of the engineering aspects of the material.

This notation is basically a three-part code system, which by a combination of letters and numbers designates the type of geologic formation in which the soil occurs identifies the soil inaccordance with AASHO Designation M , and indicates the prevailing or average subsurface drainage conditions.
