本文首先借助于极限平衡方程以及莫尔-库仑强度理论,建立计算双滑块安全系数的表达式,然后,以该表达式作为目标函数,利用优化理论探讨了双滑块最厄险滑动面的确定方法。并在安全系数为最小的条件下,讨论了滑动面几何参数之间以及它们与安全系数之间的关系。 In this paper, firstly, by using the limit equilibrium equation and the Mohr-Coulomb strength theory, an expression for calculating the safety coefficient of a double-slider is established. Then, using this expression as an objective function, the optimization theory is used to discuss the most dangerous sliding surface of a dual-slider. Determine the method. Under the condition that the safety factor is minimum, the relationship between the geometric parameters of the sliding surfaces and their safety factors is discussed.
