摘要
基于Midas Soilworks软件,采用多滑动面试算法分析某公路边坡的稳定性。该方法采用定义多圆心点和多半径计算多个可能的滑动面安全系数,分析方法快速便捷,并可以控制划分土条的宽度,从而提高极限平衡法分析土坡稳定性结果的精度和准确性。还选取有代表性的参考文献中的实例进行对比验证,证明文中分析方法的可行性和可靠性。根据分析结果,该公路边坡两次开挖后的边坡最小安全系数均满足规范要求,边坡安全,不需加固。
This paper uses the software of Midas Soilworks to analyze slope stability with multi-sliding surfaces.This method calculates safety factor of many possible sliding surfaces with many circle centre points and many radius.This analysis method is quick and convenient,and can control the width of soil strips which is divided.Then it can improve the accuracy of stability analysis with limit equilibrium method.This paper chooses some examples of representative references to verify the feasibility and reliability of this analysis method.According to the analysis result,the minimum safety factors of the highway slope which is excavated two times can meet the requirement of code.The slope is safe,and needs not to be reinforced.
