利用IDS探地雷达对隧道进行初期支护质量检测，沿隧道纵向布置7条纵向测线进行探测，获取对应测线上的初衬厚度等数据。通过图像判定和检测结果进行分析，得到围岩与初支是否脱空，进而指导施工是否继续进行。%IDS underground radar is used for tunnel initial support quality inspection. 7 longitudinal survey lines are disposed longitudinally along the tunnel, to obtain the early lining thickness and other data of the corresponding survey line. Through the image and the test results, we can judge whether the surrounding rock and early support is void, and then decide whether to continue the construction.
