地震作用下堆积层斜坡动力响应规律研究

Dynamic response research of accumulated layer slope in condition of earthquake

运用有限差分软件FLAC 3D建立数值模型,分析了堆积层滑坡在不同地震波条件下,自身地形地貌条件对其加速度场的影响和变形破坏特征,揭示动荷载作用下堆积层斜坡的动力响应规律。

The FLAC 3D is used to establish a series of numerical models,and the input seismic wave intensity and internal factors of the slope are changed to carry out numerical simulation calculation.According to the acceleration data of the monitoring points arranged in the model and the analysis law of displacement change data,the accumulated layer is summarized.The response law of layer slope under earthquake action.
