With the rapid development of the engineering actions in the highland with particular stratigraphic sequence, because of the buildings at the back of the sliding body and the cutting slope at the front, the pushing force of rock and soil in slope increased, but the anti-sliding force weakened. On the other hand, during the rainfall surface water immerged into the layer interface of the diatomite along the unloading cranny, resulting in the diatomite becoming soft after absorbing water and its shear strength lowered. At the time, the water level went up, the dynamic water pressure and uplift pressure increased, the anti-sliding force continued to reduce. Therewithal, the landslides occurred along sliding surfaces with small tilt angle.

在丘陵区此独特的层序地层近年来随着人类工程活动强度的增大，滑体后缘建筑，前缘切坡，造成下滑力增加，抗滑力减弱；另一方面在降雨的作用下，地表水体沿着卸荷裂隙通道浸入到下伏硅藻土层界面，硅藻土吸水软化，抗剪强度减弱，同时地下水水位上升，动水压力和扬压力加大，抗滑力进一步降低，于是产生了低倾角滑面滑坡。
