上下并行矿山法隧道施工相互影响研究

Research on Mutual Influence of Tunnel Construction with Up and Down Parallel Mining Method

本文以在建的台州市域铁路S1线羊头山隧道与杭绍台高铁下北山隧道为例,两隧道上下并行,最近水平距离12.45m,最小垂直距离2.46m,本文探讨了两隧道施工时序,通过全过程施工工况分析总结,探讨了并行隧道施工时序影响问题。

This paper takes the Yangtoushan Tunnel of Taizhou Municipal Railway S1 Line and the Xiabeishan Tunnel of Hangshaotai High-speed Railway as examples.The two tunnels are parallel up and down.The nearest horizontal distance is 12.45m and the minimum vertical distance is 2.46m.This paper discusses the construction sequence of the two tunnels.Through the analysis and summary of the whole process of construction conditions,the influence of parallel tunnel construction timing is discussed.
