混凝土结构的无损检测是工程界普遍重视的问题,也是保证结构安全的关键。在介绍探地雷达法无损检测原理方法基础上,以水工输水隧洞衬砌混凝土为被测对象,应用探地雷达法对衬砌混凝土厚度、内置钢筋分布、内部缺陷等进行测试、标识,并与钻芯法取芯检测结果比较,分析探地雷达法无损检测数据的精确度和偏差程度。结果表明:探地雷达法无损检测结果可信度高,能满足工程建设质量控制的要求,其在水利工程无损检测的应用是可行的。
混凝土結構的無損檢測是工程界普遍重視的問題,也是保證結構安全的關鍵。在介紹探地雷達法無損檢測原理方法基礎上,以水工輸水隧洞襯砌混凝土為被測對象,應用探地雷達法對襯砌混凝土厚度、內置鋼觔分佈、內部缺陷等進行測試、標識,併與鑽芯法取芯檢測結果比較,分析探地雷達法無損檢測數據的精確度和偏差程度。結果錶明:探地雷達法無損檢測結果可信度高,能滿足工程建設質量控製的要求,其在水利工程無損檢測的應用是可行的。

The non-destructive test of concrete structure is the importent problem in civil engineering field and is regarded as the key to ensure safety and durability of large concrete construction .Based on the in-troduction of rule and method of non-destructive test on ground-penetrating radar , the paper took hydrau-lic tunnel lining concrete as the measured object , and applied ground-penetrating radar method to test and verify concrete thickness , internal rebar distribution and internal defect .Through the comparison between the detection results by ground-penetrating radar and that by drilling core ,it analyzed the precision and deviation of ground-penetrating radar method .The research shows the results of non-destructive test by ground-penetrating radar method are reliable and can meet the requirement of quality control in construc -tion of engineering , the application of non-destructive test in water conservancy engineering is feasible .
