摘要
针对上海软土地区深埋地层某盾构区间开挖布置全断面土体扰动位移量测,对盾构开挖土体扰动特性进行各阶段监测和记录分析,并对深部地层土体扰动进行分析。根据实测数据进行对比研究,研究结果表明在上海软土地区深埋条件下,盾构掘进所产生的土体扰动在横断面为2D范围,纵断面为1D范围,盾尾脱出阶段相比盾构掘进阶段的扰动较大,约比掘进阶段的土体扰动位移大1倍。
A whole section measurement is installed to measure the displacement of soil disturbance in deep soft soil region of Shanghai. Monitoring and recording analysis is carried out aiming at soil disturbance characteristics in shield excavation. According to the comparative study of measured data, it can be concluded that the range of soil disturbance caused by shield tunneling is 2D in cross-sectional direction, 1D in vertical-sectional direction. Additionally, the displacement of the soil disturbing in shield tail prolapse stage is larger than twice as the one in shield tail digging phase.
