摘　　要：在丽江至香格里拉铁路金沙江大桥的岩石边坡稳定性分析中,岩体的抗剪强度是对边坡进行稳定性评价和确定治理方案的前提。基于此,介绍了3种以室内岩石试验及现场工程地质调查为基础的抗剪强度估算的方法,并以金沙江大桥丽江岸边坡为例,对这3种方法的适用性进行了讨论分析,获得了合理、有效的力学参数。In the stability analysis for the rock slope along Jinshajiang Bridge on Lijiang-Shangri-la Railway, the shearing strength of rock mass is the precondition for the slope stability evaluation and control scheme determination, based on which three methods estimating the shear strength depending on indoor rock test and field geotechnical investigation were introduced. Next, taking the slope along the bank of Lijiang at Jinshajiang Bridge as an example, the applicability of these three methods was discussed with the reasonable and effective mechanical parameter obtained.
