【Abstract】 The seismic time-histories responses for a loess cave under various earthquak e actions are analyzed by applying FEM in this paper. The actual problems ar e solved by the plane strain and three-dimension models respectively. The failure mechanism and weak parts of the loess cave are determined under earthquake actions in the analysis. Finally, the numerical results are in accordance with the investigation results of the actual seismic disasters .更多还原
