摘　　要：位于岩溶地区的水库工程由于复杂的地质情况,常出现渗漏问题,威胁水库安全。旱岩水库运行时间长,位于岩溶区域,工程安全问题多,急需进行除险加固。水库周围存在许多细小渗漏裂隙以及溶洞渗漏点,通过先进的环氧树脂化学灌浆材料以及CW系列灌浆工艺的三步灌浆法经过灌浆加固,对加固区域进行试验,测定灌浆加固效果良好,水库透水性减弱,灌浆后的岩溶裂隙岩芯完整度高,成功的对水库渗漏点进行防渗补强。Reservoir projects located in karst areas often encounter leakage problems due to complex geological conditions,posing a threat to reservoir safety.Hanyan Reservoir has a long operating time and is located in a karst area.There are many safety issues in the project,and it is urgently needed to carry out hazard removal and reinforcement.There are many small leakage cracks and karst cave leakage points around the reservoir.Grouting reinforcement is carried out using advanced epoxy resin chemical grouting materials and the three-step grouting method of the CW series grouting process,and experiments are conducted on the reinforcement area.The results indicate that the grouting reinforcement effect is good,the permeability of the reservoir is weakened,and the integrity of the karst crack rock core after grouting is high.The anti-seepage reinforcement of the reservoir leakage point has been successfully carried out.
