昆明柴石滩水库溢洪道是该水库的唯一泄洪设施 ,溢洪道高边坡的稳定 ,直接影响工程的施工进度和安全运行。该高边坡岩石组成复杂 ,岩体风化破碎 ,山高坡陡 ,造成边坡不稳定。为经济合理、安全有效地治理该高边坡 ,经分析研究 ,多方案比选 ,采用了削坡减载 ,加抗滑桩及坡面空心注浆锚杆系统加固等措施的综合治理方案
Kunming Chaishan reservoir spillway is the only flood discharge facility of the reservoir. The stability of the spillway high slope directly affects the construction progress and safe operation of the project. The high slope rock complex composition, rock weathering broken, steep mountain slopes, resulting in slope instability. In order to economically, safely and effectively manage the high slope, comprehensive control measures such as slope reduction and load reduction, reinforcement with anti-slide piles and hollow grouting anchor system on the slope have been adopted through analysis and research and multiple plan comparison
