摘要
针对某隧道发生严重病害路段,主要采取地下水追踪试验,结合地质调查,分析岩溶隧道衬砌病害快速发展关联因素,理清断裂构造、岩溶发育、富水条件、围岩空洞等因素是衬砌病害发展的客观作用条件,证明地表塌陷增强地下水对岩溶隧道衬砌的动力作用,可为富水岩溶地质塌陷区运营隧道的设计与维护提供参考。
It is rather high probability about operating tunnel lining seepage in geological condition of karst rich water which results in severe disasterto threaten operating tunnel. The paper analyses the development trend by lots of ways which takes geological survey, detecting, groundwatertracer test etc. We find following factors including fracture structure, rich-water, and surrounding rock cavity are objective reason resulted in deterioratingtrend of lining defect. Second, surface subsidence strengthens dynamic mechanism of underground water which prompts the interactionbetween lining defect deteriorating and surface subsidence. Finally, the paper content provides reference for maintaining and treating of operatingtunnel at karst subsidence area.
