摘要
大断面单拱隧道中隔墙具有复杂的受力特性及施工特点。以崂山隧道为例,通过理论分析、数值模拟及现场试验的方法,模拟隧道掌子面开挖过程中已经浇筑的中隔墙的受力变化,并根据模拟结果,优化施工技术,提出隧道衬砌与中隔墙墙顶分离施工的施工技术,并在崂山隧道中隔墙施工工程中成功进行了应用,取得了较好的效果。
For the large section of single arch tunnel wall complex mechanical characteristics and construction characteristics, through theoretical analysis, numerical simulation and field test, simulation of tunnel face excavation process has been pouring wall stress changes, and according to the simulation results, put forward the construction technology of masonry wall top and middle wall separation construction the tunnel lining, and the tunnel wall construction project in Laoshan in the success of the application, achieved good results.
