摘　　要：对西部项目依托工程典型土体抗剪强度参数采用不同试验方法进行测试,包括现场大剪试验、原状土室内直剪试验、原状土室内三轴试验及原状土室内周期性浸泡试验。采用层次分析法(AHP)对不同试验方法得到的强度参数进行归一化处理,并建立了综合强度参数取值原则及方法,避免了人为取值的随意性和试验的误差性。该试验研究成果已应用于库区依托工程,并取得了良好的效果,为库区滑坡滑动面强度参数取值提供了有力的参考。Typical soil shear strength parameters undisturbed soil laboratory direct shear test, undisturbed cyclic immersion test, were tested by different methods. of the western area support project including site cut test, soil laboratory triaxial test, and undisturbed soil laboratory AHP method was adopted to unify the strength parameters obtained by different test methods, and comprehensive strength parameters＇ adoption principle and method were given, for the purpose of avoiding the randomness of artificial adoption and errors of tests. The result of the experiment has been applied to the support project of the reservoir area and got satisfactory achievements. Thus the research result may serve as a reference for strength parameters＇ adoption of slide at reservoir area.
