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。
According to the engineering example of a subway station pit, the semi-empirical semi-empirical formula is used to estimate the excavation of the foundation pit and the settlement of the soil around the pit caused by the lowering of pressure water pressure. The calculation results of the soil settlement and the site So as to put forward some conclusions and control suggestions for pit-induced soil subsidence due to excavation of foundation pit and lowering of pressure-bearing water for reference of similar projects.
