摘要
针对北京地铁复 八线王府井至东单区间隧道,地外繁华闹市,两侧高楼林立,地面交通繁忙,地下管网密布,施工难度和风险极大的特点,以三维有限元理论分析为先导,模拟计算了5种情况的施工效应,成功地解决了复杂洞群条件下洞室施工的安全转换,并对复杂洞群系统施工工艺进行了优化,解决了一系列施工中的难题,取得了很好效果。
The tunnel between Wangfujing and Dongdan in Beijing Subway (Line One from Fuxingmen to Bawangfen) locates in downtown area with high buildings on both sides of the street, busy ground transportation, underground pipes network densely distributed as well as tremendous difficulties and risks in construction. In light of these characteristics, construction effect for 5 situations has been calculated in simulation with three-dimensional finite element theoretical analysis as the guide, successfully realizing the safe conversion in cave construction under complex cave conditions. Meanwhile, the construction technique in complex cave system has been optimized and a series of difficulties in construction has been solved with good effect.
