对土坡及其基础的破坏问题,从本世纪初就积极进行了研究,随后出现了许多新的概念和理论,但大多数问题都是围绕着抗滑安全系数进行讨论,圆弧滑动型破坏的理论可用图(1)来说明,安全系数的计算公式为: FS=Σ(抗滑力矩/驱动力矩) Since the beginning of this century, many studies have been carried out on the problems of soil slope and its foundation. Many new concepts and theories have emerged. However, most of the problems are discussed around the safety factor of anti-sliding. The theory can be shown in Figure (1) to illustrate the safety factor is calculated as: FS = Σ (anti-slip torque / driving torque)
