摘要

以天津地铁一号线工程为背景，通过现场实测得到了盾构推进过程中地表的变形规律和隧道周围土体的扰动规律。利用有限元程序ABAQUS的单元生死技术模拟盾构前进过程，并对工程盾构开挖过程进行了仿真模拟。结果表明计算值与实测值吻合良好。

Abstract

The ground settlements and the disturbance of soil around tunnel by shield driven are summarized by means of measurement of Tianjin No.1 subway line project. According to the actual engineering

a 3D FEM model is proposed to simulate the excavating of shield tunnel by means of general FEM program ABAQUS; the model change method is put forward to imitate moving-forward shield process. And the results of simulation are compared with the results of measurement.
