建基面呈复杂折面阶梯状的重力坝抗滑稳定分析,目前尚没有统一和完善的方法.基于三维刚体极限平衡理论以及条分法,将坝体看作由若干刚性滑动体组成的重力坝,提出了一种抗滑稳定分析方法)))三维抗滑稳定条块法,并设计编制了相应的计算程序.采用ANSYS前处理模块的荷载计算方法,以某重力坝7号岸坡坝段为例进行了分析计算,结果表明:不同工况下该重力坝7号岸坡坝段抗滑稳定安全系数均能满足规范要求.该法计算理论较严谨,且与现行规范匹配性好,可供类似工程参考.

@@@@There are no common and perfect methods for the anti2sliding stability analysis of gravity dam w ith the complex multi2 zigzag plane base surface. Based on the 32D rigid body lim it equilibrium theory and slice method, the dam body can be regarded as the gravity dam composed of many sliding rigid bodies, and a new anti2sliding stability analysis met hod, named as 32D anti2 sliding stability slice method, w as proposed in this paper and its calculation program was also developed. T he load calculation met hod using the preprocess module of ANSYS w as applied to analyze the anti2sliding stability of NO. 7 bank dam of a hydro2 pow er station. The results show ed that the anti2sliding safety factor of this dam section can satisfy the requirement of standard. This method has strict computational theory and is compatible with the current standard, and thus it can be used for references for similar project s.
