摘要
在大坡比TBM顺坡掘进过程中,隧洞涌水及TBM施工废水对施工影响较平洞TBM隧洞开挖的危害更为显著。本文通过对新疆某项目水文地质资料分析,以及在TBM开挖过程中隧洞水流特点及危害进行分析,针对其特征与危害,结合实际施工中的实践,总结出一套以强排为主,局部设置辅助排水的综合性排水系统,有效解决了类似项目中的排水问题。
In the process of tunneling along the slope of a large slope than TBM,the impact of tunnel gushing and TBM construction waste water on the construction is more signifi cant than the harm caused by fl at tunnel TBM tunnel excavation.This paper analyzes the hydrogeological data of a project in Xinjiang,and analyzes the characteristics and hazards of the tunnel water fl ow during the TBM excavation process.According to the characteristics and hazards,combined with the actual construction practice,a set of A comprehensive drainage system with auxiliary drainage has been set up to eff ectively solve the drainage problem in similar projects.
