| 摘 要： | 地下开挖引起的地表沉降是地铁修建过程中非常关键的问题.在文章中,以盾构法施工的某地铁隧道试验段的实测地表变形数据,分析了地表变位的特点,得到几点定性规律,并用Peck公式对实测点进行拟合,发现沉降曲线与正态分布曲线非常接近.将拟合结果与以往经验公式进行了对比,发现两者吻合较好.

| Abstract: | Based on settlement monitoring deformation of ground surface that results from a test shield tunnel, the characteristics of movement of ground surface are analyzed, and several qualitative laws are obtained. Using professional software to model deformation curve of ground surface, it can be found that the trough profile is similar to normal distribution (namely Gauss distribution). Finally, a comparison between fitting results and previous experienced formulas is made, and a good agreement can be obtained. |
