| 摘 要： | 以杨房沟水电站高线混凝土系统边坡危岩体为背景, 在现场调查的基础上, 分析危岩体边界特征, 提出了倾倒式、滑塌式、坠落式3种失稳模式, 建立了不同破坏模式的稳定性分级标准, 对危岩体稳定性进行了定性地质分析和定量计算, 结果表明9处危岩体在暴雨或地震作用下均存在极大失稳可能, 提出了防护措施, 实践证明防护效果良好。

| Abstract: | Take the unstable rock masses of the altitude concrete system of Yangfanggou hydropower station as a background. Based on investigation on spot and geological analysis, the boundary characteristics of the unstable rock-masses are analyzed; and the unstable rock-masses may to be failure through three modes: shear-sliding, rip-ropple and shear-falling is proposed; the stability classification standards of the different failure modes are established; the stability of the unstable rock-masses is analyzed by qualitative geological analysis and quantitative calculation. The results show that the nine dangerious rock-masses are highly likely to be failure under the action of rainfall or earthquake. Some protective measures are put forward, and the facts prove that the measures are successful and useful. |
