摘要
某水库处于岩溶发育地区,先导孔钻孔以及先导孔物探测试和施工期进一步揭示水库防渗线溶蚀率情况发生了巨大变化。通过有针对性地对原有防渗帷幕设计方案进行优化,制定了岩溶发育区的帷幕灌浆技术要求,从施工的可操作性、检查情况、工程投资可控性等多方面看取得了较好的效果。该岩溶发育区的处理方案必要且合理,其经验可供类似工程参考。
A reservoir is located in karst area where the pilot hole drilling,geophysical test of the pilot hole and the construction period further reveal that the dissolution rate of the impervious line of the reservoir has changed greatly.By optimizing the original impervious curtain design scheme,the technical requirements of curtain grouting in karst area are formulated,and good results are obtained from the aspects of construction operability,inspection situation,project investment controllability,etc.The treatment scheme of this karst area is necessary and reasonable,and its experience can be used as reference for similar projects.
