| 摘 要： | 对已建地铁车站进行技术改造是一项非常复杂、风险极大的工程,需对改造结构进行技术评估,并涉及对原结构设计内力和位移附加增量的有效控制。文章针对苏州地铁1号线金鸡湖西站已建成的地下车站的围护、主体结构局部改造设计与施工存在的风险,运用有限元数值模拟分析预测结构附加应力和变位,为控制改造施工安全提出了结构构造措施和监测措施等合理化建议,可供类似工程提供借鉴。

| Abstract: | Restructuring a previously built metro station is very complex and involves great risks since it requires technical evaluation as well as the effective control of the designed internal forces and additional displacement effects on the original structure.Focusing on the risks in design and construction associated with the local restructuring of a main structure and envelope of a built metro station,this paper predicts the additional stress and deflection of structure by using the finite element numerical simulation and presents some reasonable suggestions. |
