Application of Acoustic-vibration Method in Tunnel Secondary Liner Void Detection |
| |
Abstract: | Based on the secondary liner void detection of a tunnel section of Huaihua-Shaoyang-Hengyang Railway, the basic principle of the acoustic-vibration detection method is discussed, the application of the acoustic-vibration method in the void detection of tunnel secondary liner is introduced and the factors causing the difference of void judgment results are analyzed, providing a reference for the further study of the acoustic-vibration method in tunnel secondary liner void detection in future. |
