摘要
山岭隧道排水系统的排水能力对运营期隧道的安全运营有着重要影响.以蒙华铁路中条山隧道为工程背景,基于伯努利方程,结合工程中的两种排水系统布置形式,推导出了排水系统的排水能力公式,并采用了CFD数值软件进行模拟,验证了理论公式的正确性,同时研究了排水管堵塞对排水系统排水能力的影响.所得结论可为同类隧道排水系统的设计和优化提供借鉴.
The drainage capacity on the drainage systems of the mountain tunnels has a great influence on the safeoperation of the tunnels. In the paper,by taking the Menghua railway of Zhongtiaoshan tunnel for example,based onBernoulli equation and combined with the existing two drainage system layout,the relationship between water pressuresbehind the secondary lining and drainage is derived. CFD software is applied to prove the validity of the theoreticalformula. Drainage capacity of the clogged drainage system is also studied. The conclusions provide the reference forthe design and optimization of similar tunnel drainage systems.
