摘　　要：水工隧洞衬砌施工过程中易产生隐蔽性缺陷,危害隧洞的安全稳定运行,因此同步开展检测对保证施工质量具有重要作用。探地雷达法属于当前较为先进的混凝土质量原位检测技术,根据该方法基础原理和数据采集及处理方法,以新疆某水利枢纽为例分析研究该方法在中孔溢洪洞衬砌质量检测中的具体应用,结果表明,探地雷达法可通过研究电磁波在衬砌结构体内传播特征对隐蔽性缺陷进行无损、经济、高效检测,可为指导后续处理方案设计提供科学的数据服务和决策支持。During the construction process of hydraulic tunnel lining,hidden defects are prone to occur,which endanger the safe and stable operation of the tunnel.Therefore,synchronous testing plays an important role in ensuring construction quality.The ground penetrating radar method is currently one of the more advanced in-situ detection technologies for concrete quality.Based on an overview of the basic principles and data collection and processing methods of this method,this article analyzes and studies its specific application in the quality detection of the lining of a spillway tunnel in a water conservancy hub in Xinjiang.The results show that the ground penetrating radar method can conduct non-destructive,economical,and efficient detection of hidden defects by studying the propagation characteristics of electromagnetic waves inside the lining structure,It can provide scientific data services and decision support for guiding the design of subsequent processing plans.
