| 摘 要： | 研究目的：在城市隧道施工过程中，地层变位的大小往往成为决定施工成败的关键因素之一。通过对因施工引起地层原始应力状态改变、土体损失、管片衬砌变形等进行分析，合理设定盾构掘进参数，建立有效土压平衡，减小对地层的扰动和地层损失，保证施工质量。研究结论：以北京地铁4号线19标段盾构工程为例，对施工开挖造成地层原始应力状态改变、地层损失引起的地层位移进行了分析，并对施工现场进行监控量测。分析和量测数据验证，合理设定土压、同步注浆、掘进速度等掘进参数，建立有效的土压平衡，即可将各项变形控制在规定的范围内。

| Abstract: | Research purposes:The scale of the displacement is essential to the successful construction of tunnel in city.The boring parameters should be decided rationally through making analyses of the stratum stress change,soil loss and deformation of pipe lining caused by shield construction for the purposes of establishing effective soil pressure balance,reducing the disturbance on stratum and stratum loss,and guaranteeing construction safety. Research conclusions: Taking the shield construction of bidding 19 of L... |
