圆弧滑坡最危险滑弧圆心位置的求解方法

METHOD OF DETERMINATING THE LOCATION OF CENTER OF CRITICAL CIRCULAR FAILURE SURFACE

综合多方面的研究成果及其工程实践，系统地论述了最危险滑弧圆心的分布规律和各种求解最危险滑弧圆心的方法及其特点和使用条件，并介绍了采用试算法和非线性规划方法的求解方法．所提出的试算法不同于传统的试算法，其不仅可应用于圆弧滑坡最危险滑面的求解，亦可应用于求解层状岩体边坡复合滑面滑坡的最危险滑面．

Combine with various research results and practices of engineering, the distribution law of center of critical circular failure surface and various methods of determinating the center of critical circular failure surface and their characteristics and applicable conditions are systematically discussed, a trial-and-error method and non-linear programing method are described. The trial-and-error method is different from the traditional one, it can not only be applied to determinate the critical circular failure surface, but also can be applied to find critical complex failure surface for stratification rock mass slope.
