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。
七裏壩水庫處于高山峽穀地區，為運行多年的病險水庫，拱壩為下遊麵加厚的單麯拱壩，壩體存在橫嚮裂縫和水平裂縫，本文通過對拱壩應力進行對比分析研究，提齣瞭拱型重力壩加固處理方案，得齣瞭除險加固後拱壩穩定安全的結論，運行結果錶明，大壩穩定、運行安全。

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.
