摘要

在现场调查分析的基础上，提出了溪洛渡水电站某危岩体的两种可能失稳模式（剪切坠落或拉裂倾倒失稳），进而建立了相应的稳定性计算极限平衡力学模型，而且对危岩体的变形和破坏特征进行了数值模拟分析，分析结果表明，危岩体抗拉裂倾倒稳定性较差，剪切坠落失稳的稳定性系数较高。在稳定性分析的基础上，计算出危岩体倾倒失稳时，安全系数为1.5时的锚固力，进而提出了危岩体加固方案：充填凹岩腔+填充裂隙+预应力锚索＋锚杆联合加固，数值模拟表明此加固方案效果良好。

Abstract

Based on investigation on spot and geological analysis

an unstable rock masses of Xiloudu Hydropower Station may to be failure through two modes: shear-falling and rip-topple is proposed; and a mechanical model for calculation of stability by limit equilibrium theory is established; and the unstable rock masses deformation and failure characteristics are analyzed by numerical simulation. The results show: stability of the unstable rock masses is relatively bad if the failure mode is rip- topple

but is good if shear-falling. Based on stability analysis

the anchor reinforcement force is calculated as 12 306 kN when safety factor is 1.5 and the failure is rip-topple; and some reinforcement measures of the unstable rock masses are put for ward follows: fill hollow of rock and fill in cracks and prestressed anchor cables and anchor bolts combination reinforcement. The results of numerical simulation show that: effect of the reinforcement measures is better.
