四川省溪口滑坡运动特征的离散元模拟

通过离散元分析拟合了溪口滑坡碎屑流的运动过程和主要特征,认为滑坡解体后是以碎屑流方式完成运移和停积过程。

DISCRETE ANALOG OF MOTION FEATURE OF LANDSLIDE IN XIKOU, SICHUAN PROVINCE

Xikou landslide located in the inverted limb of Baoding anticline of Huayong anticlinoria. The strata is falling home,and the upper is hard, the lower is soft. It is beside the fault. The hard is dolomite and the soft is mudstone. There are fault calcibreccia in the landslide,and the calci-breccia are coherent mass, intact rocks only. In the paper, a playback of the deformation and motion of Xikou Landslide has been maken with discrete analog method. The result of inversion shows that the front mass of landslide is the biggest deformation early. The mass is pushed by upper sliding mass,and there are some displace and upward deformation. They are flow of debris and clast in motion and resting process after landslide disintegrate.
