浅析深埋富水地区隧道渗漏水病害注浆整治

On Grouting Treatment for Leakage Water of Deep Buried Tunnels in Water Rich Area

目前国内很多运营隧道面临病害问题,其中隧道内部发生渗漏水现象是较为高发的病害之一,尤其是很多深埋富水地区,因岩体裂隙发育,渗漏水病害的发生,使得隧道周边围岩长期受水环境浸湿,会降低围岩承载力,原始水压力场发生变化,混凝土衬砌易受压破裂,由此诱发隧道发生其他形式的病害。而且还造成隧道周围水系的破坏,影响原有生态平衡,造成环境灾害。针对深埋隧道,岩体裂隙发育,通过流固耦合对渗流场进行分析,采用ANSYS软件提供的热传导分析部分的有限元方法来求解渗流问题,再对比解析解及现场监控资料为深埋隧道漏水病害注浆堵水设计提供参考。

Currently a lot of tunnel face problems,The inside the tunnel occur infiltration and Water Leakage phenomenon is one of the high incidence of the disease,Especially a lot of deep water rich area,Because the rock,Leakage water disease,The surrounding rock by the water soaked long,Will reduce the bearing capacity of surrounding rock,The original water pressure field changes,Concrete lining stress rupture,Other forms of the disease induced by tunnel. But also caused tunnel surrounding water damage,affect the ecological balance,causing environmental disaster. According to the deep buried tunnel,rock,the fluid solid coupling of seepage field analysis,Finite element method is part of the heat conduction analysis by ANSYS software to solve seepage problem,Then by comparing the analytical solutions and the monitoring data of deep buried tunnel Water Leakage disease grouting design reference.
