摘　　要：滑坡滑带土抗剪强度参数是滑坡稳定性分析和治理工程设计的最基本、最重要参数,它的大小及其变化直接影响到滑坡稳定性的计算,并由此得到不同的结果和涉及到治理措施的有效性。通过室内试验、滑带土现场原位大剪试验、反分析值及相似滑坡类比法综合确定三峡库区金乐滑坡滑带土的抗剪强度参数,指出该滑坡滑带土抗剪强度参数的确定和分析应采用多种方法,才可获得合理可行的结果。Shear strength parameters of landslide sliding zone soil are the most important and basic parameters for landslide stable analysis and governance engineering design, and its size and changes can directly influence the stability calculation of landslide, and then we can obtain different results and be involved in effectiveness of control measures.The paper is about the determination of shear strength parameters, mainly comprehensive determination of shear strenghth of Jinle lanslide slip zone by laboratory test results ~ field shear test of landslide slip layer ~ back analysis method and theory of analogy comparison, and it is pointed out that the determination of shear strength parameters of landslide sliding zone soil must use various approachs.
