上海某地铁车站深基坑周围土体沉陷研究

Researches on soil settlement around deep excavation of a metro station in Shanghai

根据某地铁车站基坑工程实例,利用一些半理论半经验性的公式分项估算了基坑开挖、降承压水引起坑周土体沉陷,并比较分析了土体沉陷的计算结果与现场实测值,从而提出了一些基坑开挖与降承压水引起坑周土体沉陷的结论和控制建议,以供类似工程参考。

The surface settlement around deep excavation resulted from excavation construction and dewatering confined water was estimated by use of semi-empirical and semi-theoretic formula based on the example of metro deep excavation. Conclusions and advises about surface settlement resulted from excavation construction and pumping confined water were put forward by analyzing the results and field data. They are instructive to similar construction.
