| 摘 要： | 通过对某基坑周围土体位移场的理论分析及其临近的地铁隧道由基坑开挖引发的变形的监测结果的分析 ,从隧道的垂直沉降、水平移动以及隧道的横向变形等角度探讨了基坑开挖对临近地铁隧道的影响。研究认为 ,一方面基坑临近隧道由于自身刚度会对基坑开挖引发的位移在一定程度上产生抵抗作用 ,另一方面这种作用使得隧道自身的横向变形进一步加剧 ,这一结论是通过隧道的收敛量测结果以及接缝的张开值量测结果得出的

| Abstract: | Based on the theoretical studies on soft ground strain field induced by the deep excavation, and the monitored deformation of the adjacent metro tunnel, the vertical settlement and the horizontal movement of the tunnel line, and the deformation of the tunnel ring is analyzed. The study results show that on one hand, the displacement of the soil is to a certain extent counteracted by the tunnel owing to the stiffness of the tunnel, on the other hand, the counteraction further caused the tunnel deformation. The conclusion above was drawn from the monitored results of the surveyed tunnel convergence and the opening gap of the joint in the tunnel segments. |
