Abstract

The engineer must deal with many many practical problems which involve the stability of earth slopes, and it is important that the have as much information as possible regarding the stabile it of slopes in the area under consideration. Some common examples include the slopes along existing highways and railroads, banks of streams, natural slopes, and slopes maintained during various types of construction operations. If the water table and geologic cross section is also known, these slopes may be analyzed for stability and reasonable results can be obtained . There are times, however, when shearing strengths cannot be determined within a satisfactory degree of accuracy.
