摘要
《岩土工程勘察规范》规定,滑坡勘察时可采用反分析方法检验滑动面的抗剪强度指标,但没有明确指出如何应用。根据滑坡勘察实例来阐述反分析方法检验滑动面强度参数的具体应用,指出其需与滑坡剖面稳定性分析评价相结合才能得出正确参数。
According to the requirements in Section 5.2.7.3 of the new ＂Geotechnical Engineering Investigation Specifications （GB50021--2009）, the back analysis should be used to examine the strength parameters of the sliding surface. However, the specifications do not explicitly suggest the back analysis procedure. This paper presents a case history of the application of the back analysis method in determining the strength parameters of a sliding surface. It is concluded that the appropriate strength parameters could be obtained by the combination of back analysis and the stability analysis of the sliding surface.
