Abstract

A two-dimensional finite element numerical model was proposed to analyze earthquake responses of gradient-changing slope based on a shaking table test. In order to study dynamic characteristics of the gradient-changing slope, seismic waves with different peak accelerations, sorts and frequencies were input at bottom boundary of the numerical model. Simulation results show that dynamic performance of the numerical model is similar to practical homogeneous soil slope. Then, numerical model was verified by comparing simulation results with test data. The results are helpful to further study on mechanism of slope stability under earthquake and the guidance for practical engineering.
