| 摘 要： | 谷坡岩体卸荷在水利水电工程边坡中是一种常见的地质现象，对岩石边坡稳定性及相关岩石工程问题有着重要的控制意义，卸荷带定量划分一直受到水利水电工程勘测与设计的重视。用于卸荷带定量划分的指标很多，比较常用的是反映岩体结构特征的量化指标。根据水利水电工程实践，讨论谷坡岩体卸荷带划分量化指标问题，提出以张开裂隙宽度、张开裂隙累计宽度、波速比作为谷坡岩体卸荷带划分的量化指标。

| Abstract: | Rock mass unloading in riverside is a familiar geological phenomenon in hydroelectric project slope，it has important significance with regard to stability of rock mass slope，as well as relevant rock engineering problem. Unloading zone quantitative classification is always high lightened by hydroelectric project survey and design，it is common to use quantitative index to reflect rock mass structure characteristics despite of many other index used for unloading zone quantitative classification. According to hydroelectric engineering practice，this paper discussed the problem how to classify quantitative index for rock mass unloading zone in riverside，and proposed to use width of opening fissures，total width of opening fissures and ratio of wave velocity as quantitative index for rock mass unloading zone in riverside. |

| Keywords: | rock mechanics rate of opening fissures width of opening fissures total width of opening fissures ratio of wave velocity unloading zone classification |
