Application of Ground Penetrating Radar in Quality Inspection of Lining in Yuxi Youyi Tunnel
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.
