| 摘 要： | 喜河水电站坝型为混凝土重力坝,重力坝对地基岩体的抗剪强度有较高的要求。前期勘查成果表明喜河水电站坝址区存在较多的缓倾角结构面,缓倾角结构面的存在是影响坝基抗滑稳定的关键,因此要对坝基作出抗滑稳定性评价。首先要研究坝址区缓倾角结构面的分布规律及连通情况,通过对坝址区缓倾角结构面的综合分析研究提出合理的坝基岩体的综合抗剪强度。

| 关 键 词： | 抗滑稳定 缓倾角结构面 连通率 综合抗剪强度 |

| Abstract: | Concrete gravity dam has been selected for Xihe Hydropower Station,and it has high demand for shear strength of rock mass in the foundation.Through exploration,many low-angle dip structural planes have been found at the dam site.Because low-angle dip structural plane is the key factor to affect the anti-sliding stability of foundation,it is necessary to evaluate the anti-sliding stability of dam foundation.Firstly,study on the distribution regularity and joint persistence ratio of low-angle dip structural planes at the dam site would be carried out.Then reasonable shear strength parameters of rock mass in the dam foundation could be suggested through comprehensive analysis. |

| Keywords: | anti-sliding stability low-angle dip structural plane joint persistence ratio comprehensive shear strength |
