【摘    要】：武漢地铁6号线一期越汉江段工程控制因素较多且施工风险较大，汉江两岸车站站位布置、功能、配线、周边建筑、交通接驳等影响到线路穿行方案，结合越江线路方案、环境特点和类似工程经验，对穿越汉江的6种通道方案在线路线型、客流吸引、设站条件、沿线拆迁、工程实施难度等方面进行综合对比，推荐采用鹦鹉大道崇仁路通道方案。结合汉江南北两岸的设站条件、江底冲刷线深度和施工难度等进行对比选定琴台站、武胜路站位；确定琴台站—武胜路站过江区间平纵断面设计方案。越江区间隧道采用直径6.2 m断面，盾构法施工，有效降低工程实施难度，确保工程安全，减小工程投资。

【Abstract】：The Crossing-Hanjiang River section project of Wuhan Metro Line 6 has many control factors and high construction risks， station layout， functions， wiring， surrounding buildings， traffic connection， etc. of the stations on both sides of the Hanjiang River affect the line travel plan. Based on the cross-river route scheme， environmental characteristics and experience of similar projects， this paper conducts a comprehensive comparative study on the route type， passenger flow attraction， station setting conditions， demolition along the line， and project implementation difficulty of the six channel schemes crossing the Hanjiang River， it is recommended to adopt the channel scheme of Yingwu Avenue and Chongren Road. Based on the station setting conditions on both sides of the Hanjiang River， the depth of the scour line at the bottom of the river， and the difficulty of construction， etc.， the Qintai Station and Wusheng Road Station are selected， which confirms its plane and vertical design scheme. The cross-river section tunnel adopts a section with a diameter of 6.2 m and is constructed by the shield method， which effectively reduces the difficulty of project implementation， ensures safety and reduces investment.

随着轨道交通建设的发展，很多城市轨道交通线路要穿越江河湖海，线路走向及两端车站线站位布置等直接影响工程建设的安全性和经济性。近十几年来武汉先后建成及在建多条穿越长江、汉江及其他湖泊的隧道 [1～5]。地铁越江工程一般都是控制性节点工程，影响整条线路的通车运营；因此，线路研究和线站位研究尤为重要。许多专家、学者对越江隧道的可行性、线路方案比选、隧道设计方法和原则[6～7]等进行了研究与探讨；但对越江隧道控制因素及不同越江方案多专业、全方位对比研究较少。本文重点分析汉江两岸车站站位布置、周边建筑、环境特点、交通接驳功能、配线等影响线路穿行方案的控制因素；……
