Abstract
The residual shear strength of the non plastic soils are generally estimated from the correlations between residual shear strength estimated from the laboratory tests or from the back analyses of post failure geometries of case histories distressed during static or seismic loading and penetration resistances. The post failure shear strength of large deformed structures like debris flow, mud flow and avalanches in which the post deformed soil mass gain large distance after the failure, depends on the strain rate behavior of shear (viscous) resistance, frictional resistance, inertial effect, three dimensional effect of geometry, flexibility of failed material and void redistribution during failure. Therefore, in this paper an energy based procedure is proposed to estimate the residual shear strengths and based on the results of the back analysis of the post failure configuration of twenty cases the correlations between residual shear strengths and stress normalized and compressibility corrected Standard Penetration Test (SPT) blow counts and Cone Penetration Resistances (CPT) considering the energy based procedure are proposed.
