Impact of tensile strength and incident angles on a soil slope under earthquake SV-waves

摘要: Abstract The tensile strength and incident angles play important roles in seismically induced slope failures. In this paper, a new criterion for tension–shear coupling is proposed based on several sets of relevant lab data verified using the experimental provided by previous researchers. This can perfectly depict tension region as well compression entire stress space. Moreover, was converted into an expression that could be directly used numerical method, it example. addition, SV-waves were input equivalent nodal force method viscous-spring artificial boundary. process implemented ABAQUS software, two examples to verify method. Subsequently, impacts analysis failures studied. results indicated evaluation extremely landslides overestimated calculation Mohr-Coulomb owing ambiguous description failure or tension-shear failure, assessment stability thus not conservative. seismic waves affected travel path directivity responses; sliding displacement side near epicenter rose with increasing wave incidence, critical slip surface deepened, hazard aggravated. Therefore, introduce both when evaluating slopes subjected loads.
