Time-Dependent Displacement Analysis of Anchored Slope Subjected to Seismic Loading Considering Nonlinear Mohr-Coulomb Failure Criterion
A time-dependent yield acceleration is adopted to estimate the seismic permanent displacement of anchored slope by establishing a dynamic failure mechanism and an instant displacement mode. A real-time equivalent tangential strength envelope is adopted to determine the time-dependent yield acceleration while considering a nonlinear failure criterion of slope soil. The recursion formulas of slope and anchor parameters versus seismic displacement are established to decouple the relationship between the time-dependent yield acceleration and the seismic displacement. The result indicates that the anchored slope becomes more vulnerable to earthquake when the nonlinear parameter of soil increases.
