为了提高地震区砂卵石地层地铁车站主体结构的安全性，利用 ANSYS 数值模拟计算基本荷载组合、标准荷载组合、地震荷载组合以及人防荷载组合情况下的内力值。通过分析得出，不同荷载组合情况下的最大内力值均出现于侧墙与底板相交处；不同荷载组合所产生的最大内力值中人防荷载组合的最大，需要予以重视；地震荷载组合的内力是非对称的，所以车站主体结构的设计需要考虑地震荷载组合。

In order to improve the main structure safety of the metro station in sand gravel stratum of earthquake zone,the internal force values of basic load combination,standard load combination,seismic load combination and civil defence load combination are calculated by numerical simulation with ANSYS. T he analyzing results showed that each maximum internal force value of different load combination appears in the intersection between side wall and floor,the internal force value of civil defence load combination is the maximum of all,which should be paid more attention,the internal force of the seismic load combination is asymmetry,which means seismic load combination should be considered in station main structure design.
