Slope stability is a critical and fundamental element of geotechnical engineering involving the assessment of existing natural slopes and the intelligent design of man-made slopes, and the factors that may cause them to survive for many years or to crumble in a land slide.Virtually every civil engineering project, and especially highway development -- currently the hottest single area in all of civil engineering in the U.S.-- involves some element of slope stabilty and stabilization methods. This is a new edition, with some 35ew material, of one of the best available guides to stability and stabilization methods.
