通过野外现场调查,室内土质试验和数值模拟,对由地震诱发的筑馆滑坡和降雨诱发的山科滑坡的流动化机制的差异进行了分析。对于筑馆滑坡,滑带土在地震作用下产生液化以后,由于土粒子破碎效应,以及火碎流堆积物的高速剪切效应所导致的高孔隙水压的产生是导致其高速远程滑动的主要原因。山科滑坡的流动化原因则为,由于饱水的风化泥岩具较低的透水性,使得滑坡体在运动中只能发挥很低的剪切强度。
Field investigation, indoor soil test and numerical simulation were carried out to analyze the difference of fluidization mechanism induced by earthquake in Zhuziluan landslide and rainfall-induced Shanke landslide. In the case of the Tsukatate landslide, the slippery zone soil is liquefied under the action of an earthquake. The generation of high pore water pressure caused by the crushing effect of the soil particles and the high-speed shearing effect of the debris of the flow crushing is the main cause of the high-speed remote sliding the reason. The reason of the landscaping landscaping is that due to the low water permeability of the saturated muddy rocks, the landslide body can only exert very low shear strength during the movement.
