| Abstract | 以杭州地铁 2 号线某盾构区间工程为背景，推导饱和软土双线盾构掘进引起的土体变形及孔压理论解，结合 实际工程参数分析土体及超孔压变化规律；控制切口附加推力、盾壳摩擦力和盾尾注浆压力的取值，研究不同施工参 数对土体竖向变形的影响。结果表明：盾构接近研究断面时，施工参数对土体变形的影响较大；当双线盾构推进通过 研究断面一定距离后，其施工引起的横向地表位移变化和切口附加推力作用下的超孔压变化趋于稳定；盾壳摩擦力对 孔压的影响范围主要集中在盾构穿越一半长度内；当双线盾构远离研究断面后，盾尾注浆作用产生的超孔压力趋近于 0； 研究结果可为杭州软土区类似盾构工程提供指导建议。 |
