摘要
针对地铁通常采用的"先站后隧"做法带来的影响车站施工安排问题,提出"先隧后站"施工工法,包括管棚法、托梁法、半盾构法、结合矿山法、扩径盾构法等。采用这些做法可缩短施工工期,减少盾构机周转次数,降低对场地的需求,技术经济效益良好。
To avoid the influence of commonly-used"station-first and tunnel-second"method on station construction arrangement,"tunnel-first and station-second"construction method was proposed,including tubular shed method,joist method,semi-shielding method,mining method and diameterexpanding shielding method,etc.It could shorten the construction period,reduce turnover of shield machine,weaken the requirements for construction site and realize favorable technical and economic benefits.
