摘要
为了解决城市轨道交通长大穿山区间工程设计过程中遇到的问题,依托厦门市轨道交通2号线区间隧道工程,重点分析了纵坡比选、工法选择、结构设计、防排水设计、防灾疏散等技术要点。在此基础上,分别论述了纵断面3种不同坡度的优缺点及选取原则,矿山法和TBM施工工法选择需考虑的主要因素,结构线别和断面设计的主要思路,防排水设计3种不同方案的主要理念,以及防灾疏散方面的主要措施,并分别推荐了相应的方案,提出了相关的建议。
To solve the problems during the design about long tunnel passing though mountain in urban rail transit engineering, the main technology points such as longitudinal slope selection,construction method selection,structure design,waterproof and drainage design,disaster prevention and evacuation were analyzed based on Xiamen Metro Line 2 section tunnel engineering.On the basis, this article respectively discussed the advantages,disadvantages and selection principles of vertical sections with 3 different kinds of slopes, the main factors to be considered in the selection of mining method and TBM construction method, the main ideas of structural line type and section design, the design philosophy of3 different waterproof and drainage schemes and the main measures of disaster prevention and evacuation.The schemes were recommended accordingly and some suggestions were put forward.
