摘  要:强岩溶地区高压帷幕灌浆施工质量直接关系到大坝结构的使用性能,乃至整个工程的成败,特别是地处强溶岩地区的水工建筑物,坝体压实度、抗渗要求高,控制难度大。如何采取切实可行的施工措施来确保帷幕灌浆施工质量,是工程项目成败的关键。本工程根据需要,结合现场条件采取了上述各个环节的施工保证措施,充分分析了强岩溶地区透水率的各项经济合理指标,选择经济合理、设计要求指标有保障的技术措施,项目施工进度的压力得到了缓解,保证了大坝防渗质量。The construction quality of high-pressure curtain grouting in strong karst area is directly related to the performance of dam structure and even the success or failure of the whole project.Especially for hydraulic structures located in strong karst area,the requirement of dam compaction and seepage resistance is high and the control is difficult.How to take practical construction measures to ensure the quality of curtain grouting construction is the key to the success of the project.According to the needs and combined with the site conditions,the construction guarantee measures of the above-mentioned links have been adopted.The economic and reasonable indexes of permeability in strong karst areas have been fully analyzed,and the technical measures with reasonable economy and guaranteed design requirements have been selected.The pressure of the construction progress has been alleviated and the seepage control quality of the dam has been guaranteed.
