摘要
七里坝水库处于高山峡谷地区,为运行多年的病险水库,拱坝为下游面加厚的单曲拱坝,坝体存在横向裂缝和水平裂缝,本文通过对拱坝应力进行对比分析研究,提出了拱型重力坝加固处理方案,得出了除险加固后拱坝稳定安全的结论,运行结果表明,大坝稳定、运行安全。
Qiliba Reservoir is located in mountain valley area,which has been operated for many years and belongs to dangerous reservoir.The arch dam belongs to thickened single arch dam on the downstream face.The dam body have transverse cracks and horizontal cracks.In the paper,arch dam stress is comparatively analyzed and studied.The reinforcement treatment plan of arch gravity dam is proposed.The conclusion of stable and safe arch dam after risk removal and reinforcement is obtained,and the operation results show that the dam is stable with safe operation.
