中峡水库混凝土砌石坝除险加固设计

Concrete masonry dam reinforcement design of Zhongxia Reservoir

通过对中峡水库病险成因的分析,采取了坝顶上游增设防浪墙、坝体补强、坝基固结灌浆、防渗帷幕灌浆、溢洪道拓宽及其下游增设消能工等加固设计措施,经过施工单位的精心施工,改造后的大坝经受了汛期的考验,治理效果良好。

Based on analysis of the causes for the problems of Zhongxia Reservoir, reinforcement measures were de-signed including construction of upstream wave wall on dam crest, reinforcement of dam body;consolidation grout-ing and anti-seepage curtain grouting at dam foundation;widening of spillway, construction of downstream energy dissipater. By careful work of construction unit, the reinforced dam has withstood a flood season, showing good rein-forcement effect.
