地铁盾构穿越建筑物施工工序的探讨

Discussion about construction process of Metro Shield passing through the building

地铁使用盾构法进行施工时,不仅要保证隧道本身的安全性,更要确保地面建筑群的稳定性,其中后者尤为重要。而地铁双向双洞的开挖工序对地表建筑物有着较为重要的影响,结合武汉市某轨道交通工程实例,使用有限元模拟的方法,分别从开挖后总位移,塑性区分布等方面综合分析,从而对地铁盾构穿越建筑物施工工序提出建议。

Constructing the subway by using the shield , it is not only needed to ensure the safety of the tunnel itself, but also to ensure the stability of the buildings on the ground , where the latter is particularly important.Subway two-way two-hole excavation process has a relatively important influence on surface buildings , com-bined with a particular engineering instance of Wuhan Rail Transit Line ,the finite element simulation method is used to do comprehensive analysis of the total displacement after excavation ,the distribution of plastic zone and other aspects respectively, in order to make recommendations on the metro shield through the building construction process.
