运营隧道的典型病害及其处治技术研究

Field Survey of Typical Disease of Operation Tunnel and Treatment Technology

在总结分析运营隧道水损害、衬砌裂损、冻害、衬砌腐蚀、偏压等典型病害诱因及其影响的基础上,通过工程实例研究病害处治技术。采取水害治理技术可有效控制结构的渗漏水现象;通过裂损处治技术修复衬砌断面缺损以及裂缝,补偿病害引发的衬砌刚度损失;冻害处治技术可防止隧道受到冻胀力作用而破坏;偏压处理技术确保了隧道的稳定性和安全性。运营隧道的病害处治技术在工程实践中有显著效果。

Based on analysis of the water damage, lining fracture, type incentives as well as the impact of frost damage lining corrosion and bias diseases, the paper studied the countermeasures through engineering examples. The water damage treatment technology can control the water seepage phenomenon of structures effectively; the dehiscence treatment technique can repair the defects and cracks of the lining section, and compensate the lining stiffness loss caused by diseases; the frost damage treatment techniques can prevent the frost heaving force; the bias processing technology can ensure the stability and security of the tunnel, which have a significant effect on the disease treatment of operational tunnel in engineering practice.
