多滑动面深层抗滑稳定求解方法探讨

深层抗滑稳定是重力坝最关注的问题之一，目前运用最广泛的计算方法主要是双滑面方法，但对于基岩分布复杂、错动带较为发育的情况，双滑面稳定计算所作的主滑面和次滑面假设，容易与实际情况产生较大偏差。针对这一问题，本文着眼于多滑动面深层抗滑稳定求解方法的探讨，建立多滑动面稳定计算的非线性方程组，并根据方程组的特点提出迭代求解方法。通过采用本文方法对某重点工程溢流坝段基岩深层抗滑稳定性进行分析，计算结果表明该方法具有更大的适用性，可为工程设计提供更好的依据。

Study on Stability against Deep Slide with Multiple Slip Planes

Stability against deep slide is a key issue for evaluating safety of a gravity dam,wihich is commonly analyzed by assuming the sliding with two sliding planes.Owing to the complexity of rock foundation,e.g.containing many shear zones,in this method the assumption of the major and secondary slip planes may lead to a remarkable deviation from the reality.In this paper study on stability against deep slide is conducted by derving the nonlinear equation to calculate the stability against slide including multipl...
