Abstract: Pile-anchor system is widely applied in slope-reinforcing engineering.The study on dynamic response of the soil slope supported with pile-anchor system subjected to earthquake wave is very important to finding out failure mechanism and seismic character of the slope, and guiding slope reinforcing design.A vertical soil slope model with pile-anchor system was established, The stresses and strains, moments and shear forces of the pile and anchor axial force were obtained.By applying seismic wave dynamic analysis of the slope applied with piles and anchors was performed, and the velocities, displacements, soil pressures, tension stresses of the slope surface, shear forces and moments of the piles, and anchor axial forces dynamic response were obtained.Moreover, pile-anchor system dynamic character was displayed, the results showed that pile-anchor system could validly control the deformation, slope stability and tension stresses on slope top surface, and had very good anti-earthquake capability.
