摘　　要：本文介绍利用中子检测新技术探查广西贵港航运枢纽工程四台发电机组尾水管钢板里衬下浇注混凝土脱空缺陷。其检测结果可指导灌浆施工和检查灌浆处理质量。该项技术是一种无损、快速、准确和安全的混凝土施工质量检测新方法。This paper describes a case testing by using neutron method for detecting inner cavitydefect in pour concrete under steel plate lining of four hydro-power generation draft tubesin Gusngxi Guigang navigation project. The test results can provide very useful information for guiding grout construction and for Inspecting grout quality. This new neutronmethod is a non-destructive,qulck reliable and safe testing technique for concrete construction quality inspection.
