天生桥二级水电站厂区下山包滑坡稳定分析及工程治理

Study of XiaShanbao Slide Developing Principle and Propertyof the 2nd Tianshengqiao Hydropower Station

天生桥二级水电站厂房后边坡坡顶，存在一处下山包古滑坡。由于边坡开挖、爆破振动以及在古滑坡体上布置施工场地和生活用水的下渗等原因，导致古滑坡的复活。本文论述了滑坡的发生机理并介绍滑坡的工程治理和监测工作的基本经验。

The Xiashanbao slide of the 2nd Tianshengqiao Hydropower Station,located on the Xiashanbao top of the slope behind the power house,is a stable one andlater,it revives as a result of excavation explosion of high slope and seepage ofconstruction and domestic water.The slide deformation developing principle and propertyis complex.During the initial stage,the traction is key and later it is inverted todisplacement.As it is a complex and typical space slide,the study is with theorotical andengineering practical significance.
