摘　　要：友谊隧道通过地段工程地质及水文地质情况复杂,还存在顺层偏压、滑坡、溜等不良地质条件以及软土、岩盐、石膏、膨胀土等特殊岩土。通过地质雷达对友谊隧道衬砌进行衬砌厚度、钢筋(钢架)分布情况、衬砌背后回填密实度以及二衬混凝土强度等工程质量检测,检测结果可以直接反映隧道衬砌结构变化情况,对后期工程缺陷整治和验收提供数据支撑和方法指导。The engineering geology and hydrogeological conditions of the section where Youyi Tunnel passes through are complex,and there are also adverse geological conditions such as bedding pressure,landslides,and landslides,as well as special rock and soil such as soft soil,rock salt,gypsum,and expansive soil.By using ground penetrating radar,the thickness of the lining,distribution of steel bars(steel frames),compactness of backfill behind the lining,and strength of the secondary lining concrete of the Friendship Tunnel lining are tested for engineering quality.The detection results can directly reflect the changes in the tunnel lining structure,providing data support and method guidance for later engineering defect rectification and acceptance.
