| 摘 要： | 目前,在地铁车站结构设计中,一般采用将荷载满布到结构模型进行内力分析,并未考虑不同活载布置对结构内力的影响,从而导致部分截面设计存在安全隐患。文章以成都地铁3号线一期工程红牌楼南站结构模型为例,运用MIDASGEN有限元分析软件对不同活载布置下结构的内力进行比较,得出地铁车站各截面控制内力所对应的活载布置,为地铁车站结构设计提供借鉴。

| Abstract: | Concerning Lot.III for deep excavation on Ningbo metro line 1, the paper pointes out the technical problems that may exist in foundation engineering and identification of sources of risk. By using expert investigation method and analytic hierarchy process （AHP）, combining risk analysis methods for quantitative assessment of the risk that may exist in the foundation excavation process, it determines level of risk and weight. The results show that,foundation excavation and construction risk weight are the biggest, being the higher in the level of risk, and the highest value in transfer node construction risks in a variety of construction risks. |
