Comparison and Selection of Renovation Schemes for Lining Cavity of Existing Railway Tunnel

近几年,铁路隧道衬砌敲击检查已成普遍趋势,隧道衬砌是列车平稳、安全运行的根本保证,对隧道衬砌安全性的要求随运营速度呈几何指数增长。前期施工遗留衬砌空洞问题对列车运营安全影响尤为显著,如何合理、有效、安全地整治衬砌空洞病害是一项重要工作。

In recent years,the knocking inspection of railway tunnel lining has become a general trend. Tunnel lining is the fundamental guarantee for the smooth and safe operation of trains. The requirements for the safety of tunnel lining increase exponentially with the speed of operation. The problem of lining voids left over from previous construction has a particularly significant impact on the safety of train operations. How to remediate lining cavity defects reasonably,effectively and safely is an important task.
