摘要: 针对建基面与特定结构面组合构成的复杂浅层和深层抗滑稳定问题, 在常规双滑面计算方法的基础上, 采用等安全系数方法的原理推导了计算公式, 并给出了方程求解方法。资料表明计算方法的边界假定符合现行规范及行业设计要求。通过例题和实际工程试算, 证明了方法的可行性, 且计算精度也能满足设计要求。可解决工程中带部分建基面的大坝失稳滑移模式的抗滑稳定计算问题。

Abstract: The calculation of shallow and deep slide-resistant stability of dam involving foundation surface and weak structural planes is very complex. On the basis of conventional method for double failure faces, the principle of equal safety coefficient was adopted to derive the nonlinear equations for stability analysis, and an iterative solution was proposed based on the characteristics of these equations. The assumptions in this solution are in line with the general requirements of current specifications and industry designs. Calculation example of a gravity dam verified the feasibility and accuracy of this solution.

Key words: foundation surface, weak structural plane, slide-resistant stability, multiple failure faces, safety coefficient
