太原地铁2号线矿机—西涧河线站位方案综合研究

西涧河站为太原地铁2号线一期工程终点站,站后未设置停车场,车站配线须满足初期折返和夜间停车。线路受现状地面纵坡、建(构)筑物、交通疏解、地震液化等因素控制,边界条件复杂。从矿机—西涧河三站两区间入手,对满足运营需求的多个备选方案,从运营组织、工程规模、交通疏解、工程风险等多方面分析比较,最终确定矿机站、小商品市场站分别为地下二层、三层岛式车站,西涧河站为地下二层一岛一侧车站的综合最优方案。

Comprehensive Study on Kuangji-Xijianhe Line Position Scheme of Taiyuan Subway No. 2 line

Xijianhe station is the terminal of the first-stage project of Taiyuan subway No. 2 line and the auxiliary lines of the station must have the ability to satisfy train turning-back and parking at night on account of the missing of the parking lot in the preliminary stage. As affected by ground longitudinal slope,buildings, traffic organization, seismic liquefaction, its boundary conditions are extremely complicated. This paper conducts analysis and comparison of operation organization,project scale,traffic management and engineering risk based on recommended schemes to meet the requirements for operation in respect of Kuangji- Xijianhe( three stations two intervals). Eventually Kuangji station and the small commodity market stations are determined to be of underground two-floor station and underground threefloor island station respectively,and Xijianhe station is of the underground two-floor,one island with one side station.
