地下2层双线同站台换乘方案研究
|
摘要
为解决目前地下2层双线同站台换乘设计方案普遍存在的土建造价高、空间浪费大、换乘比例受到一定限制、车站前后区间交叉多、联络通道设置不方便、施工风险大等问题,通过对5、9、12m3种地铁车站站台层中间线路的左右中心线间距方案进行比选,选取12m线间距方案为综合最优方案,扩大后的空间可设置设备用房或换乘站台;同时,根据实际换乘客流情况,选择合理的地铁线路左右线布置方案。通过实例分析可知:通过采用新的布置方案,此类同站台换乘车站前后区间均可采用盾构法施工,不需要在区间设置竖向联络通道,从而可以减少明挖车站长度,降低车站和区间的综合造价,同时减少区间的平面交叉,降低施工风险;增设换乘站台的方案还可以增加车站同站台的换乘比例。
The transfer design of underground two-floor double-line metro tunnel with same platform is characterized by high cost, large space waste, limited transfer proportion, multiple intersections in front and back of the station section, inconvenient cross-passage setting and high construction risk. Hence, 3 schemes of different spacings between right central line and left central line, 5 m, 9 m and 12 m, are put forward and compared, in which the spacing of 12 m is the optimum and can be used as equipment room or transfer platform; meanwhile, rational layout scheme of right line and left line should be determined according to the actual transfer passenger flow. The case study results show that by adopting the above-mentioned scheme, the sections ahead of and behind the station can be bored by shield, no vertical connection gallery should be constructed, the length of open-cut station can be shortened, and the cost, at-grade intersection of section and construction risk can be reduced; the transfer proportion can be increased by adding transfer platforms.
