摘要

规划修建的深圳地铁11号线车公庙车站紧贴地铁1号线和丰盛町商业街围护结构

为确定设计方案可行性

基于三维有限元数值分析方法

考虑地下水情况

针对分别采用盖挖逆筑、明挖顺筑施工工艺的地铁车站结构受力情况

开展了地铁车站施工期间及后期围护的结构变形分析

确定了不同施工工艺对地铁车站围护结构的影响。研究结果表明:①虽然2种施工工艺在地铁车站施工过程中都能很好地降低地下水位

但是盖挖逆筑施工完成后

孔隙水压力值与周围土体内孔压值的差距相对明挖顺筑施工较大

极易造成毗邻地下结构向基坑内侧倾斜;②盖挖逆筑施工工艺下

毗邻地下结构横向变形相对较大;③在基坑施工过程中

应对1号线车公庙车站加强支护和监测

防止其产生较大变形。

Abstract

The Chegongmiao subway station is adjacent to the first subway of Shenzhen and Fengshengding shopping street

which is on the Shenzhen 11th subway to be constructed.To determine the design scheme feasibility and assure the station structure safety and operation normality

the 3D finite element method is investigated to simulate the different construction technologies and deformation of exterior-protected construction.By simulating the stresses of subway station under sheltered reverse excavation and open excavation

the effect of different construction methods on subway station is analyzed.The engineering measures to reduce the influence of construction are supported for determining the construction plan.It can be found that:（1） two kinds of construction technology in the subway station construction process can well reduce the underground water level

but the gap between pore water pressure of soil in the foundation and around the foundation after the sheltered reverse excavation is completed

is bigger than those of the open excavation obviously.The leaning is caused extremely easily adjacent to the underground structure.（2） The lateral deformation of building under sheltered reverse excavation is relatively large.（3） During the foundation construction process

the first subway station structure should be supported and monitored to prevent the large deformation of the structure
