HYDROGEOLOGICAL CHARACTERISTICS OF LANDSLIDE GROUP IN XIAOSHENG TOWN,FENGSHUN COUNTY,MEIZHOU CITY
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 F10,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.
