摘要
以某地铁车站为计算实例,分析了浅埋地铁车站的荷载取值和结构计算问题。通过有限元计算,分析了地下水位、水压力折减因数、侧压力因数、弹性抗力系数等因素对结构受力的影响,总结了影响规律,提出在地铁车站结构计算中应考虑这些因素变化造成的影响。
A numerical analysis on subway station is conducted in this paper to show the loading and structure calculation problems for the shallow-buried structures in urban area. The effect of the influential factors, such as groundwater level, waterreduction coefficient, lateral pressure coefficient and elastic resistant coefficient are examined by FEM. Finally, some suggestions referring to these factors are given for future design works.
