摘　　要：北京地铁 5号线崇 (文门 )—东 (单 )区间渡线大断面全段穿越明清密集民房区 ,为确定合适的超前预加固措施 ,有效控制沉降 ,分别对水平旋喷和大管棚方案进行计算和分析 ,并从工期和经济方面进行对比 。The crossover of Chongwenmen-Dongdan section of Beijing Metro Line 5 goes through dense dwelling houses. To determine appropriate advance pre-strengthening measure and effectively control ground settlement, computation and analysis was made of horizontal chemical churning pile and large pipe roof, and comparison was made between the two schemes with respect to construction period and economy.
