清平水库坝基覆盖层工程地质特性的研究

Study on Engineering Geologic Property of Dam Foundation Overburden at Qingping Reservoir

通过钻探、物探、触探、竖井及各种试验研究了解了清平水库坝基覆盖层砂卵石层的物理力学性质,为软基建坝提供了充分的地质依据。对西部大开发中的水利水电建设具有普遍意义。

Physical mechanical property of sand and gravel layer in overburden of dam foundation at Qingping reservoir is known from drilling , geophysical prospecting , penetration sounding , shaft and other tests . This provides sufficient geologic basis for dam construction on soft foundation and is of general significance to construction of water conservancy and hydropower projects in West Development .
