摘　　要：为了建立JRC-JCS模型下的点安全系数计算方法,并对岩体边坡各部位稳定性进行评判,首先推导基于JRC-JCS模型的非线性点安全系数计算公式。然后,研究JRC-JCS模型参数对于点安全系数的影响,并通过算例分析,编制相应的点安全系数程序,应用于边坡各部位岩土体的稳定性分析中。研究结果表明:编制的计算程序的结果与FLAC3D的计算结果一致,从而验证了程序的正确性,并且该程序结果能够反映边坡岩体各部位的稳定情况。In order to build the calculation method of point safety factor based on JRC-JCS model, and to estimate the stability of each part of rock slope, firstly, the calculation formulation of nonlinear point safety factor based on JRC-JCS model was founded, and then the effect of parameters of JRC-JCS model to the point safety factor was studied. And through calculation example, the program of point safety factor was compiled in the application of stability analysis for each part of rock slope. The calculation results show that the results from the compiled program is in accordance with the FLAC3D calculation results, which has verified the correctness of the program, and the program results can reflect the stability of each part of rock slope.
