摘　　要：以齿坎式挡土结构物的现场抗滑试验为依据,运用非线性弹性有限元方法,对齿坎长度分别为0、0.7m和1.0m的挡土结构物的现场试验进行了理论分析,研究了位于软弱地基中的挡土结构物中的齿坎抗滑机制,其有限元理论分析能很好地表征现场试验成果,并运用强度折减的有限元方法对齿坎式挡土结构物进行极限设计,该理论研究可为工程设计提供齿坎抗滑作用的设计理论。Based on the field tests of the retaining wall with tenon, three-dimensional nonlinear elastic finite element method has been developed to analyze theoretically the field tests of the retaining wall with tenon of 0, 0.7 m and 1.0 m length. The sliding resistance mechanism of the tenon of the retaining structure in the soft ground has been researched. The finite elements theoretical analysis results are consistent with the testing results. The strength reduction finite element method has been applied to the limit design of retaining structure with tenon finally. This theoretical study results provide a theory of sliding resistance of tenon for engineering design.
