三线换乘车站换乘节点结构计算分析
|
摘要
研究目的:一个城市的轨道交通路网,必然存在着两线或两线以上的相交,构成了多种形式的换乘。同时还要考虑与地面铁路客站、航空站、地面大型公交枢纽站、轮船码头和公路客站等接近换乘。由此,换乘车站是地铁车站的重要枢纽站,设计分析均较为复杂。重庆地铁6号线一期工程冉家坝车站为三线换乘车站,需要对换乘节点区域进行三维分析,为设计提供理论依据,保证车站结构的安全。研究结论:本文结合冉家坝车站的三维模型分析,提出了换乘节点区域应力配筋的设计方法;根据换乘节点厚板的受力特点,提出了双向板布置模式;根据中柱受力情况,提出了型钢混凝土柱方案;根据TBM过站模拟的分析,提出了轨行中板的TBM荷载用临时支撑承载与结构使用功能的永久荷载结构承重的方案。
Research purposes: In an urban rail transit network,there must be two lines or above intersecting to form various forms of transfer,and at the same time the transfer to the ground railway station,airport,major ground bus hub,ferry and road passenger station should be considered.Thus,the transfer station is an important hub for subway,and its design and analysis are rather complex.The Ranjiaba Station of the first-phase project of the Line 6 of Chongqing subway is a transfer station and it is necessary to make the three-dimensional analysis of the transfer regional nodes for providing a theoretical basis for the design to ensure the safety of the station structure. Research conclusions:Based on the analysis of the Ranjiaba Station with the three-dimension model,the design method for the stress reinforcement in the transfer node region is offered.According to the load-bearing characteristics of the plate thickness of the transfer node,the double-plate arrangement mode is presented.According the load-bearing situation of the middle column,the scheme of the steel section concrete column is given.Based on the simulation analysis of TBM passing the station,the scheme of bearing the TBM load with the rail-mounted middle plater by temporary support and bearing the structure load by the permanent load-bearing structure is pointed out.
