摘要

研究目的:在城市地铁线路设计中,城市现有构筑物及地下工程状况等多种因素均对工程设计起着限制作用。本文针对深圳地铁1 号线罗湖至大剧院段构筑物密集、地下桩基复杂的不利因素,研究探讨更适合的线路布置方式,解决本工程的设计难题,并为类似工程的线路设计提供经验。
研究结论:罗湖至大剧院段首次在国内采用左右线上下重叠的布置方式; (2) 线路重叠设计,较常规或传统设计模式下布置的隧道,所占用的地下空间减少 25% ~55%,且增加线路选线自由度,解决了拥挤空间内的布线难题; (3) 线路重叠设计,横向占用的空间最小,更有效地避让两侧的建筑物基础; (4) 采用地下三层侧式车站,车站管理和乘客使用不便,同时线路转换段的坡度设计有"剪刀差",左右线上下坡度较大,不利运营; (5) 转换段线形复杂,施工困难,不宜过长,否则运营后的振动会造成上下线洞体间的土体液化而引起隧道沉降; (6) 类似线路设计时,应注意线路埋深、平行与重叠的转换段、重叠段、重叠段两线高程差等问题,要与建筑专业和隧道专业相互沟通、密切配合,确保综合经济效益,同时降低施工风险。

Abstract

Research purposes:In the track design of urban metro,the existing structures and the underground engineering,etc. set a limit to the project design. Aiming at the unfavorable factors of crowded structures and complicated underground piles countered in the section between Luohu and Grand Theater of Line 1 of Shenzhen metro,the study was done on the more appropriate track arrangement to solve this problem and provide the experience to thesimilar works.
Research conclusions:(1) In the section between Luohu and Grand Theater of Line 1 of Shenzhen metro,it was the first time in China to use the right track and the left track with the arrangement of the up - down overlapping. (2) Compared with the traditional arrangement,such track overlapping arrangement could reduce the space occupation by 25 - 50% and enhance the freedom of the track alignment to solve the problem of the track laying in the crowded space. (3) The lateral space was occupied least by using the track overlapping arrangement and it effectively kept away from the building foundation. (4) If the three - storey side station was used,it was inconvenient for the station management and passenger travel and made the gradient in the track switching section having the " scissors difference" with the big gradient of the right and left tracks and it was unfavorable for the operation. (5) The switching section was inappropriate to be over long because of the complicated line-shape and difficult construction. Otherwise,after service,the tunnel settlement would happen because of the liquefaction of the soil between the tunnels. (6) When designing such track,the attention would be paid to the track 's buried depth,parallel and overlapping switching sections,switching section and difference in elevation between the tracks in the overlapping section,and the communication and cooperation would be conducted between the persons of the architecture and tunnel closely to achieve the economic benefits and reduce the construction risk.
