摘　　要：清凉山隧道竣工以来,由于隧道穿越砂、页岩互层围岩,地下水丰富,页岩易于风化且遇水发生膨胀崩解,使隧道拱部多处出现裂纹及渗水,危及行车安全。为保证行车安全,对该隧道进行了地质雷达无损检测,为整治设计、施工和维修提供了参考数据和资料。Since the completion of Qingliangshan Tunnel, cracks and water infiltration occurred at the arch part of the tunnel due to its passing through the surrounding rock of sandstone and shale inter-bedding, abundant underground water, the easy weathering of shale and its expansion and breaking to water, and this will endanger the driving safety. For the purpose of safe drivage, non-destructive inspection was made with geologic radar in order to provide reference data and information for the renovating design, construction and maintenance of the tunnel.
