下坪水库除险加固工程方案优化设计

Reinforcement engineering scheme optimization of Xiaping reservoir

针对下坪水库运行15 a后,出现淤积严重、建筑物破坏严重等问题,威胁下游安全,需要对该水库进行除险加固.从技术、经济等方面对大坝加固方案和原坝体防渗处理方案进行优化比选,确定了最终除险加固方案.

For the problems of serious silting and construction destruction in Xiaping reservoir after 15 years operation,downstream safety was threatened,therefore,the reservoir need to be reinforced to eliminate danger.Dam reinforcement scheme and the original dam seepage prevention plan are optimized from the technology and economy,and the final strengthening project is confirmed.
