This one-of-a-kind, definitive reference offers expansive coverage of geotechnical engineering for civil engineering professionals. It brings together essential information related to the evaluation of engineering properties of soils; design of foundations such as spread footings, mat foundations, piles, and drilled shafts; and fundamental principles of analyzing the stability of slopes and embankments, retaining walls, and other earth-retaining structures. It covers soil dynamics and foundation vibration to analyze the behavior of foundations subjected to cyclic vertical, sliding and rocking excitations. This definitive reference also details environmental geotechnology and foundations for railroad beds.
