United States Army Corps of Engineers, 1981


This ETL prescribes guidance, developed from presently acceptable structural and geotechnical principles, in the form of equations for evaluating the factor of safety of single and multiple plane failure surfaces under both static and seismic loading conditions. Basic considerations for determining shear strength input parameters for the analysis are discussed. Minimum required factors of safety are established for both the static and seismic loading conditions. Background describing the development of the previously used shear-friction and resistance to sliding design criteria for evaluating the sliding stability of gravity hydraulic structures, and the basic reasons for replacing the old criteria, are included in inclosure one. Example problems for single and multiple wedge systems are presented in inclosure two. An alternate method of analysis is discussed in inclosure three.
