文章在传统土坡稳定性分析Fellenius条分法的基础上做出改进,结合泰勒图表确定土坡圆弧滑裂面的圆心,利用几何关系构建各参数变量的关系,基于计算机语言C++,设计了土坡稳定安全系数的简单程序,并采用教材经典例题进行验算,通过改变参数变量获得不同条件下土坡的安全系数。计算结果简明、可靠,程序设计思想可为更复杂的土坡稳定性计算提供参考。

In this paper, the traditional Fellenius slice method for soil slope stability analysis is improved. The center of the circular slip surface of the soil slope is determined by combining the Taylor diagram. The relationship between the parameters and variables is constructed by using the geometric relationship. Based on the computer language C++,a simple program for the safety factor of soil slope stability is designed, and the classical examples of teaching materials are used for checking. The safety factor of soil slope under different conditions is obtained by changing the parameter variables. The calculation results are concise and reliable,and the program design idea can provide references for more complex soil slope stability calculation.
