中文摘要：
目前,江西省水利工程质量检测多采用取芯法或回弹法检测混凝土实体质量,传统的检测方法难以检测混凝土内部缺陷,同时,存在时效性和适用性不强的缺点.本文结合混凝土挡墙工程的实际检测环境,采用地质雷达无损检测方法,以提高检测效率,客观高效地实现对水工混凝土质量的控制.该方法基于波的反射定律,通过对地质雷达接收波进行信号分析,判断目标物的位置、形状、缺陷等,用以分析混凝土的施工质量.将地质雷达检测方法应用于浯溪口水利枢纽混凝土挡墙工程质量检测中,对比分析地质雷达检测法与钻芯法检测结果,表明：地质雷达法能够很好的应用于混凝土挡墙工程质量检测,与传统检测方法相比具有无损、快速和高效的特点,在水利工程混凝土质量检测方面具有很好的应用前景.
英文摘要：
Currently the quality of concrete entity in water conservancy projects of our province is mostly tested using core - drilling or rebound method, which can hardly detect the inner defects within and lack of timeliness and feasibility. Consider- ing the actual testing environment, this paper uses the nondestructive testing method of GPR （ground penetrating radar） to enhance detection efficiency and achieve quality control of hydraulic concrete objectively and efficiently. This method is based on the reflection law of wave and verifies the location, shape and defection of target object by analyzing the signal re- ceive by GPR. After applying GPR in the quality test of the concrete retaining wall in Wu Xikou hydro - junction, compara- tive analysis between the test result of GPR and core - drilling method shows that- the GPR is suit for quality test of con- crete retaining wall ; the GPR quality test is nondestructive, fast and efficient compared to traditional methods ; it＇ s of great application prospect in concrete quality test in hydraulic engineering.
