华阳河水库大坝存在坝基渗漏和绕坝渗漏的问题,同时坝体浸润线抬升影响下游坝坡的稳定性,需要进行除险加固处理。本文针对性地提出坝顶改造、坝坡加固、坝体防渗墙及坝基帷幕灌浆等综合治理加固措施,并进行了加固前后地下水渗流和坝坡稳定计算,对加固效果进行阐述和分析。 The dam of Huayanghe reservoir has seepage problems of dam foundation and seepage around the dam. At the same time, the upwelling of the dam infiltration line affects the stability of the downstream dam slope and needs to be treated for reinforcement and reinforcement. In this paper, we proposed the comprehensive improvement measures such as dam roof reconstruction, dam slope reinforcement, dam body cut-off wall and dam foundation curtain grouting. The groundwater seepage and dam slope stability calculation are made before and after reinforcement, and the reinforcement effect is expounded and analyzed.
