Based on an accumulation slope field test induced by road cutting to glide,a three-dimensional finite element model was set up.Deformation of accumulation slope is simulated.Horizontal displacement rule of ZK1,ZK2 and ZK3 observation points with excavation depth is obtained.The results calculated by three-dimensional finite element model were in comparison with the field test results and well consistency was found to confirm that the finite element method can be used to simulate the slip surface and the sco...
