摘要
望京隧道是北京至沈阳铁路客运专线的一座城市铁路盾构隧道,也是全线控制工期工程,因此有必要重点研究该隧道盾构段的施工总体筹划方案。基于54个月的工期要求,该隧道盾构段研究了两个施工总体筹划方案,并从工期和经济两个方面综合比较两个施工总体筹划方案的优缺点,确定相对优化的推荐方案。结果表明:在满足工程安全和工期要求的前提下,城市隧道盾构段的总体筹划方案还需考虑拆迁工程对方案的可实施性和经济性的影响。
Wangjing tunnel is a urban railway tunnel on Beijing-shenyang dedicated passenger railway line and also a controlling project of the entire line. Thus, it is necessary to study the overall construction planning of the shield segment. Two schemes are proposed based on 54 months of construction period in view of the construction period and the economy. The advantages and disadvantages of the two schemes are analyzed to identify the better one. The results show that the impact of resettlement on the applicability and economical efficiency of the plans should be taken into consideration.
