摘要
通过两维和三维数值模拟计算,详细分析了上海轨道交通11号线南段工程大直径盾构区间隧道内设置中隔墙对隧道结构的影响。根据隧道发生均匀沉降和不均匀沉降两种工况,分别计算了隧道管片的轴力、剪力、弯矩和最大主应力,计算结果为该隧道设计提供了重要的参考依据。
Combined with the southern project of Shanghai Rail Transit Line No.11,through two-dimensional and three-dimensional numerical simulation,a detailed analysis was made to the effect of division wall in running tunnel on large-diameter shield running tunnel.The axial force,shear force,bending moment and the maximum principal stress of tunnel segment were calculated under the two conditions(tunnel occurring even settlement or differential settlement).The calculation results will provide important refe-rences for the tunnel designer.
