| 摘 要： | 通过直剪模型试验和非线性有限元分析，研究了由结构面和岩桥组成的剪切面在不同法向应力、不同岩桥面积及不同岩桥分布型式等条件下的综合抗剪强度，较客观地评价了岩桥对剪切面抗剪强度指标的影响，初步探讨了岩桥的破坏机理。

| Abstract: | In this paper, through model test and non liner finite element analysis of direct shear model, sythetic shear strength of shear plane including discontinuity and rock bridge is studied in consideration of various normal stress, rock bridge persistant ratio and rock bridge distribution. The effect of rock bridge on shear parameters of shear plane is discussed, and the mechanism of rock bridge failure is revealed. |

| Keywords: | discontinuity rock bridge shear plane sythetic shear strength |
