摘要
截至目前,浙江省双向8车道小净距公路隧道的设计建造案例并不多,富阳市大盘山隧道出口段(双向8车道,开挖宽度21.3m,开挖高度14.16m,最小净距约10m)是大断面小净距隧道的典型代表。论文依托大盘山隧道工程,考虑大断面、小净距隧道分部开挖的影响,开展隧道开挖施工全过程的数值分析,并对隧道施工过程中的结构安全性进行评价,以期为同类隧道设计施工提供工程经验。
Up to now,there were few design and construction cases of two-way eight Lane small clear distance highway tunnel in Zhejiang Province.The exit section of Dapanshan tunnel in Fuyang City(two-way eight lane,excavation width 21.3m,excavation height 14.16m,minimum clear distance about 10m)was a typical representative of large section small clear distance tunnel.Based on Dapanshan tunnel project,considering the influence of divisional excavation of large section and small clear distance tunnel,this paper carried out the numerical analysis of the whole process of tunnel excavation and construction,and evaluated the structural safety in the process of tunnel construction,in order to provide engineering experience for the design and construction of similar tunnels.
