| 摘 要： | 基于龙东路-世纪公园站区间隧道现场实测资料，对由盾构施工引起的沉降槽的形状进行了深入研究。首先绘出埋深不同的沉降槽的实测形状；再利用数学拟合方法对沉降槽的形状、影响范围、宽度系数及最大沉降量出现的位置进行的研究，指出它们均与隧道的埋深有着密切的关系；最后，用统计学的方法给出隧道埋深与最大沉降量以及沉降槽宽度系数与隧道埋深之间的定量关系式。

| 关 键 词： | 横向沉降槽 隧道埋深 宽度系数 最大沉降量 |

| Abstract: | The settlement trough induced by the shield construction is researched deeply based on the raw test material in situ in metro section between Longdong road and Century Park; the relationships between the shape of settlement, influence scope, width coefficient, the location where the largest settlement appears and the depth of the tunnel, are presented. And the quantitative relations between largest settlement, the width coefficient and the depth of the tunnel are given using the statistical method. |
| |
| Keywords: | across settlement trough tunnel depth width coefficient largest settlement |
