STABILITY CHARTS FOR EARTH EMBANKMENTS

Two new charts are presented for the stability analysis of earth embankments. The chart for short-term stability is based on the phi equals 0 analysis and can be applied to a nonhomogeneous slope composed of various soil layers, and that for long-term stability is based on the c, phi analysis and is applicable only to a homogeneous slope. The major advantage of these charts compared with those currently available is their simplicity. They can be used by practicing engineers to determine the factor of safety of a proposed embankment or to check the reasonableness of a computer solution. With discretion, the charts can be applied to a variety of cases encountered in engineering practice. Examples demonstrate the application of these charts to the stability analysis of earth embankments. The factors of safety obtained from the new charts are compared with those from the ICES-LEASE computer program, based on the simplified Bishop method, and are found to be in good agreement.
