摘　　要：三峡双线船闸地下输水系统结构设计复杂,由平、斜、竖隧洞和竖井错落相贯构成了庞大的地下洞室群,施工历时4 a共完成混凝土浇筑59.18万m3。确保混凝土质量优良对双线船闸的正常运行有至关重要的作用,为更好地检查混凝土的内部浇筑质量,采取了混凝土无损检测的措施,并结合检测结果进行钻孔取芯检查。The underground water filling and emptying system of TGP double lane shiplock is complicated in structure, and the various tunnels and shaft well form a huge underground cavity group. The construction underwent 4 years with grouted concrete of 591.8 thousand m3 . The concrete quality has an important role in operation of the shiplock. In order to well check internal concrete quality, non-destructive check measures was taken and testing and verifying were conducted by core boring.
