Abstract
The Xuanzhenguan Tunnel on Lanzhou-Chongqing Railway that was constructed in horizontally interbedded layers of mudstone and sandstone. There once appeared crushing of the sprayed concrete, uplift of the tunnel invert and cracking of concrete liner. Based on in-situ monitoring, laboratory experiment and numerical simulation, the forensic investigation of the damages occurred were performed with proper treatments proposed accordingly. Finally, the treatments presented in this paper were proved to be effective.关键词
