库什塔依水电站左坝肩边坡处理设计

KuShenTaYi Hydropower Station Left Abutment Slope Treatment Design

通过对左坝肩卸荷岩体边坡地质条件和工程特性研究,左坝肩边坡不存在滑动破坏的底滑面。计算表明,不存在发生大规模整体滑移式失稳的可能。通过采取工程措施对坝顶高程以上边坡削坡减载、挂网喷混凝土防护和预应力锚索加固综合处理后,左坝肩边坡的安全性明显提高。

This article through to the left dam shoulder of unloading rock mass slope geological conditions and engineering characteristics of side slope of the left dam abutment,there is no sliding failure of the bottom surface,calculation shows that,there is no large-scale integral sliding instability may.By taking engineering measures on the crest elevation of above slope cutting slope unloading,shotcrete net protection and prestressed anchor reinforcement treatment,side slope of the left dam abutment safety improved.
