摘　　要：水文地质特征复杂是控制小胜镇滑坡群稳定性的重要因素之一。滑坡群存在地下水补给地表水,地表又以面流形式下渗补给地下水的现象。其中风化壳网状裂隙富水带主要分布于北侧山体及滑坡体内强风化花岗岩中;断裂构造裂隙富水带分布于北侧钻探推测断裂F_(10)及侵入岩与砂岩接触带,既充当富水带又充当导水带,该断裂构造裂隙富水带具承压性,产生水压力,增大下滑压力,易推动滑坡滑动。The complex hydrogeological characteristics is one of the important factors controlling the stability of landslide group in the Xiaosheng Town.The landslide group has a phenomenon where groundwater replenishes surface water,and the surfaceflow infiltrates and replenishes groundwater.The water-rich zone in network fissuresof weathering crust is mainly distributed in the strongly weathered granite in the northern mountain and landslide body.The water-rich zone of fracture structure is distributed in the north side of fault F_(10),speculated by drilling,and the contact zone between the intrusive rock and sandstone.It serves as both a water-rich zone and a water conducting zone.The water-rich zone of fracture structure has pressure resistance,which could generate water pressure,increase sliding pressure,and thus easily promote landslide sliding.
