某水电站左岸的大型松散堆积体在汶川地震中出现了局部变形破坏,但未产生整体破坏现象。应用FLAC3D软件对该松散堆积体的地震响应进行数值模拟分析,对其在强震作用下的稳定性及变形破坏特点进行分析,表明该堆积体在地震作用下的稳定性良好,只会在局部出现变形破坏,整体失稳的可能性不大,并且模拟结果与地震后该松散堆积体的实际稳定状态一致。

A loose deposit beside a large-scale hydropower station appeared local deformation and failure in Wenchuan earthquake,but did not produce overall destructive phenomenon.In this paper,FLAC3D software was used to make numerical simulation to the seismic response in this loose deposit,and to analyze its stability and failure characteristics under the strong earthquake.The results show that the loose deposit stayed stable under seismic action and only appeared local deformation and failure without the possibility of whole stable-lose.In addition the simulation results are consistent with the actual stable state of the loose deposit after earthquake.
