简要介绍了一下Coulomb-Mohr屈服准则的基本原理、内容及其在模型和算法中的优缺点,继而用等效Coulomb-Mohr屈服准则对Coulomb-Mohr屈服准则进行了修正,算例结果表明,算法更容易收敛,且边坡安全系数偏小,更利于工程设计的安全性。
The basic principles and contents of Coulomb-Mohr yield criterion and their advantages and disadvantages in models and algorithms are briefly introduced. Then the equivalent Coulomb-Mohr yield criterion is used to correct the Coulomb-Mohr yield criterion. The results show that the algorithm Easier to converge, and the slope safety factor is smaller, more conducive to the safety of engineering design.
