【Abstract】 The concepts of the steadystate deformation and steadystate strength were expounded, and a method was proposed for analysis of the earthquakeinduced liquefaction of saturated sand and the slope stability based on the steadystate strength. In this method, the void ratio and relative compactness of sand were determined by the field test data first; then the field curve of steadystate strength was deduced based on the curve obtained in laboratory tests; finally conclusions on sand liquefaction and slope stability were drawn after a comparison of the driving shear stress with the field steadystate strength after earthquakes. Furthermore, a detailed flow chart for calculation was developed by reference to previous research results.更多还原
