交通荷载对基坑围护结构变形特性的有限元分析

Finite Element Analysis of Deformation Characteristics of Foundation Pit Retaining Structure under Traffic Load

根据某地铁车站工程的地质特点和条件,采用有限元方法分析了交通荷载对地铁车站基坑围护结构变形的影响规律,并与实测结果进行了对比。结果表明交通荷载作用下基坑变形明显增大,并且随着基坑开挖深度的增加,总体呈增大趋势。研究结果对其他相似工程有借鉴意义。

According to the geological characteristics and conditions of a subway station project, the influence laws of the deformation of the metro station foundation pit retaining structure under traffic load are analyzed by finite element, and compared with that of the measured results. The results show that the deformation of the foundation pit is obviously increased under the effect of traffic load, and the general trend is increased with the increase of the depth of the foundation pit excavation. The research results can be used for reference in other similar projects.
