| 摘 要： | 在前人研究成果的基础上归纳总结了几种确定岩体质量参数m，s值的方法，并结合长江三峡工程永久船闸高边坡岩体，进行岩体质量参数m，s值对岩体强度影响的研究，得到岩体质量参数m，s值与Hoek—Brown强度包络线以及瞬时内摩擦角φi等之间的一些变化规律。对于研究岩体质量参数对岩体强度的影响有一定的应用价值和参考价值。

| Abstract: | Based on the research works of predecessors, some methods of determining rock quality parameter m, s value are induced and summed up. The study of impact on the rock quality parameter m, s value to rock strength are executed in combination with high rock slope of the permanent navigation lock for Three Gorges Project on the Yangtse River. Then variable patterns are not only obtained m, s value to Hoek- Brown strength envelope curve, but m, s value to instantaneous internal friction angle φi. There have certain applications and references to study the impact on rock quality parameter to rock strength. |

| Keywords: | rock quality parameter rock strength Hoek- Brown strength criterion envelope curve instantaneous internal frictionangle |
