地质雷达在地铁隧道深度探测中的应用

根据大连地铁5号的工程实例,运用瑞典地质雷达对隧道区间进行深度探测,分别介绍了溶洞、裂隙、富含水以及软弱夹层探测中雷达图像的特征。给予了一些施工建议,提早预防工程灾害。可以为地质雷达在隧道不良地质深度探测中积累一些经验并为以后相似工程提供借鉴。

Application of Geological Radar in Metro Tunnel Depth Detection

With the rapid development of subway construction ,accidents occur frequently during the subway construc-tion ,so it is very important to detect the bad geological condition and its depth to the ground .Taking Dalian Metro Line 5 project as an example ,the Swedish geological radar was adopted to detect the tunnel depth ,the cave ,fissure water rich soft interlayer ,according to the radar image some construction suggestions were given ,to prevent engineering disasters . The research can provide some experience for the geological radar in the detection of bad geological condition of tunnel and provide reference for similar projects in the future .
