摘　　要：随着城市地铁网络的不断扩张,地铁隧道的建设与维护变得尤为重要。混凝土衬砌是地铁隧道结构的关键组成部分,其质量直接影响隧道的安全性和使用寿命。该研究旨在探讨地铁隧道混凝土衬砌质量检测方法,重点关注了超声波法和雷达法这两种非破坏性检测方法。结果表明:超声波法主要用于测量混凝土的密度、声速、裂缝、包含水的情况,以及钢筋的深度和位置等表面和浅层参数;雷达法适用于检测混凝土结构的内部缺陷、钢筋的位置、混凝土层厚度等深层结构的信息。With the continuous expansion of urban subway networks,the construction and maintenance of subway tunnels have become increasingly important.The concrete lining is a critical component of subway tunnel structures,and its quality directly impacts the safety and service life of the tunnels.Therefore,this study aims to explore quality inspection methods for subway tunnel concrete lining,with a focus on two non-destructive testing methods:ultrasonic testing and radar testing.The results indicate that ultrasonic testing is primarily used to measure surface and shallow parameters of concrete,including density,sound velocity,cracks,water content,and the depth and location of reinforcements.On the other hand,radar testing is suitable for detecting internal defects in concrete structures,the position of reinforcements,and the thickness of concrete layers.
