Analysis and Evaluation of Secondary Lining Thickness Detection and Safety of High-speed Railway Tunnel |
| |
| Abstract: | Through the detection of the ground penetrating radar method for the secondary lining of a high-speed railway tunnel with a design speed of 350 km/h, the defects of the secondary lining structure were found and summarized; a finite element model based on loading-structure method is established, and the safety factor of the secondary lining structure under different defect degrees is calculated and summarized, looking forward to providing a certain reference for the future treatment of tunnel secondary lining diseases. |
