恒山水库左坝肩稳定问题及加固探讨

Discussion on Stability and Consolidation of Left Abutment of Hengshan Reservoir

恒山水库左岸坝肩存在着抗滑稳定问题 ,影响大坝安全运行。经过对左岸坝肩抗滑稳定分析 ,结合地形地质条件 ,对左岸坝肩岩体建议采取固结灌浆、预应锚索加固措施 ,并对岸边陡崖岩体进行喷锚防护 ,防止陡崖岩体进一步风化破坏 。

The stability against sliding of Hengshan Reservoir left abutment is a remaining issue which affects the safe operation of the dam. After analyzing the stability against sliding of the left abutment and considering the topographic and geographic conditions, it is suggested in this thesis that consolidation grouting and pre-stressed anchorage cable be adopted to solve this problem. In addition, the steep rock body on the bank should be protected by shotcreting and anchoring measures to prevent further weathering and ensure the safe operation of the reservoir.
