摘　　要：岩溶区坝基渗透稳定的控制对水库稳定安全运行有重要意义。以云南省某水库坝基为实例,针对其存在的岩溶渗漏问题,采取帷幕灌浆的工程处理措施。在帷幕灌浆布置的基础上,通过灌后检查孔来检验灌浆质量,采用透水率与单位注入量的相关性变化来评价灌浆效果。结果表明,该帷幕灌浆方案的灌浆效果良好,能满足工程帷幕防渗要求。研究成果可供类似工程参考借鉴。The control of seepage stability of dam foundation in karst areas is significant to the safe and stable operation of reservoir.Taking a dam foundation of a reservoir in Yunnan Province as an example,the engineering treatment measures of curtain grouting are taken to solve the karst leakage problem.On the basis of curtain grouting arrangement,the quality of grouting is tested by checking the hole after grouting,and the effect of grouting is evaluated by the correlation between water permeability and unit injection amount.The results show that the curtain grouting scheme has good grouting effect and can meet the requirements of anti-seepage of project curtain.The research results of this paper can be used for reference for similar projects.
