| 摘 要： | 以深圳地铁五号线的盾构施工为工程背景，对洪浪站-兴东站区间盾构隧道的施工进行了监控量测，根据实测数据，对土压平衡盾构法隧道施工引起的土体变形特性进行了分析，研究了地表沉降过程及其分布规律，结合理论研究与三维数值计算，将有限元模拟结果与实测数据进行对比，二者吻合程度较好。

| Abstract: | Taking shield construction on Metro Line 5 in Shenzhen as the engineering background, the construction of the shield tunnel from Honglang Station to Xingdong Station was monitored and measured. Depending on the measured data, the characteristics of soil deformation caused by tunnel construction by means of soil pressure balancing shield is analyzed; and the course of ground surface settlement and its distribution law are studied. Combined with theoretical research and three-dimensional numerical calculation, the comparison between the result of finite element simulation and the measured data is carried out to show the match condition is good. |
