3-D DYNAMICAL RESPONSE ANALYSIS OF SLOPE IN SOUTH SIDE OF FUSHUN EAST OPEN-PIT MINE UNDER EARTHQUAKE

摘要

In order to evaluate the infection of earthquake in south side of Fushun eastern opencast mine, in this paper, the geology model was analyzed thoroughly, the 3-D model was established using ANSYS program. The earthquake wave was input. The dynamic response analysis of slope is applied, and the stress, displacement, velocity and acceleration are researched. The results indicated that various kinds of stresses had stresses concentration phenomenon in the bottom of slope. Because the value of the stresses was less, any plastic shape did not appear in slope. The velocity magnifying effect and acceleration hysteretic effect were discovered.Slope dynamic response and stability under earthquake action get common attention in engineering field and academe. Slope dynamic response and stability under earthquake action get common attention in engineering field and academe. In this paper, the dynamical response of slope in south side of FunShun East Open-Pit Mine was analyzed by FEM. The response of the stress, displacement, velocity and acceleration were researched to support reasonable dynamic safety evaluation for this slope.
