垭塘水库除险加固设计

Reinforcement Design for Yatang Reservoir

广西区内水库众多,尤以小型水库居多。为探究小型水库普遍存在的病险问题及除险加固工程措施手段,以垭塘水库除险加固为例,结合前期安全鉴定结果,分析了水库现状及存在的问题,并对主要枢纽建筑物的加固方案进行对比分析,提出采用大坝防渗墙、坝基帷幕灌浆、输水隧洞扩建、引水坝拆除重建等措施。除险加固后有效地解除水库存在的病险隐患,发挥水库正常的灌溉效益,可为类似工程提供借鉴。

There are many water reservoirs in Guangxi region,especially small reservoirs.In order to explore the common problems and reinforcement measures of small reservoirs,taking the reinforcement of Yatang Reservoir as an example,combined with the previous safety appraisal results,the current situation and existing problems of the reservoir are analyzed,and the reinforcement schemes of the main hub buildings are compared and analyzed,and measures such as dam anti-seepage walls,dam foundation curtain grouting,water conveyance tunnel expansion,and diversion dam demolition and reconstruction are proposed.After the reinforcement,the hidden danger of the reservoir can be effectively removed,and the normal irrigation benefit of the reservoir can be brought into play,which can provide reference for similar projects.
