| 摘 要： | 通过室内模型试验分析研究了城市中盾构隧道施工对邻近基坑围护结构的影响效应与影响规律。研究结果表明:盾构开挖面到达将诱发监测断面处,较大增幅地下连续墙墙身附加应变;而当开挖面超过监测断面约1.7D,地下连续墙墙身附加应变将趋于稳定;盾构动态穿越施工将导致邻近侧向地下连续墙角部墙身底部与中段墙身中部出现较为明显朝向隧道的弯曲变形。

| Abstract: | Laboratory model test is used to investigate the influence to the retaining structure due to adjacent dynamic shield tunneling. The analytical results reveal that there is a larger increase of the additional diaphragm strain caused by the arrival of the shield excavation face, while the additional diaphragm strain will be stable by the shield excavation face passing the monitoring section about 1.7D. Besides, the obvious bending deformation towards the tunnel will appear at the bottom of the corner diaphragm wall and middle of the central diaphragm wall caused by adjacent dynamic shield tunneling. |
