摘　　要：极限平衡法、滑移线法是求解剪切破坏模式下均质岩基极限承载力的两种重要的极限分析法。通过对某工程均质岩基承载力的反算 ,对基于Hoek -Brown经验强度准则的 3种极限承载力计算方法—Bell解、Hoek -Brown解和滑移线法的计算结果进行了比较 ,并分析了造成差异的原因。Equilibrium method including Bell solution and Hoek-Brown solution and characteristic method are the main methods to determine ultimate bearing capacity under shear failure with Hoek-Brown strength criterion. In order to compare the calculating result of characteristic method with equilibrium method, an example in Chongqing was offered in the paper.It was shown that Bell solution was better fit for the calculation for ultimate bearing capacity of isotropic rock foundation.
