溃屈型滑坡滑面强度特征及在稳定性预测中的意义——李家峡水电站初期蓄水水库滑坡预测成功原因分析

THE STRENGTH CHARACTERISTICS OF SLIDE SURFACE OF BULKING LANDSLIDE AND ITS SIGNIFICANCE FOR STABILITY FORECASTING——A successful forecasting of reservoir landslide at Lijiaxia Hydropower Station at the preliminary stage of storage

溃屈型滑坡由于滑动破坏方式的不同，滑面的物质组成有明显的差异。按照物质组成的特征对滑面强度参数进行分段试验、取值，是作好此类滑坡稳定性预测的重要环节。以李家峡水库Ⅱ号滑坡为研究实例，介绍了作者们在滑坡预测成功方面所取得的研究成果。

There is evident diversity in material composition of slide surface of bulking landslide,due to the difference of failure patterns.It is an essential link in stability forecasting of bulking landslide to carry on test sectionally and get the consequent strength parameters of slide surface according to the characteristics of its composition.The study results in this field is indroduted in this paper, taking No.2 landslide of Lijiaxia Reservoir as an example.
