摘　　要：通过对某厂滑坡以粘土岩为滑带土的工程特性的研究,结合降水入渗,滑体内饱和带地下水压升高,由高含量蒙脱石亲水矿物组成的粘土岩滑带土,具有典型的膨胀土属性。降水入渗后使滑带土水化、泥化,基质吸力显著降低,抗剪强度下降,导致滑坡稳定性降低、滑移,是诱发滑坡变形复活的主要作用机理。Through the research of the engineering characteristic of the lime factory＇s landslip with clayey rocks in slippery band soil, together with infiltration of precipitation, and the rising of groundwater pressure of saturation band inside the slippery substance, and the clayey rocks in the slippery band soil which has high contents of montmorillonite hydrophilic miner inflation soil. After the infiltration of precipitation,it will make the slippery band soil hydrate, turn into clay, and cause the suction of the base quality fall observably, the strength of the anti-shear weaken, and the stability of the landslip lower. Slippage is the mechanism which has the main functions to place a premium on the landslip transmutation.
