摘要
以北京某地铁车站深基坑工程为背景,采用FLAC3D有限差分软件对实际基坑工程进行三维数值模拟,在保证基坑自身安全的前提下,分析了预加轴力对土体水平位移的影响,并确定了合理的预加轴力范围,使基坑开挖对周围土体水平变形的影响减至最小.
Based on the deep excavation engineering in a subway station, the FLAC3D software used to simulate the practical engineering is introduced in the paper. On the primise of ensuring own security of excavation, the effect of pre-axial forces on the soil displacement is analysed and the scope of reasonable pre-axial forces is defined.
