摘　　要：青岛地铁五四广场站采用盖挖半逆作法施工。通过Plaxis软件对吊脚桩进行建模,分析其受力及变形情况,采用MIDAS GEN软件分析了钢管混凝土立柱柱脚的复杂受力情况。仿真分析及验算结果表明,吊脚桩和钢管混凝土立柱的受力及变形情况均满足要求。The semi-reverse method of cover and excavation is adopted for the construction of May Fourth Square Station in Qingdao metro.Software Plaxis is used to establish a sling pile model,then analyze its stress and deformation conditions.The MIDAS GEN software is used to analyze the complicated stress of concrete filled steel tubular column.The result of simulation analysis and checking shows that stress and deformation of the concrete filled steel tubular columns and the sling pile could meet all the requirements.
