摘要
常州市轨道交通1号线聚湖路站整体为单柱双跨整体钢筋混凝土结构形式,明挖法施工,3号出入口为地下一层框架结构。现计划新建聚湖路站与武进万达广场联通口项目(以下简称“联通口项目”),拟建立包含市政通道、车站结构及附属结构的三维数值模型,分析新建市政通道对既有车站结构及附属工程的位移变化规律。研究结论表明:车站总位移5.147mm,出入口竖向位移最大值约为7.442mm,水平位移最大值1.548mm,均满足控制指标要求。联通口在开挖阶段对既有结构的影响最为明显,所以须在施工时加强保护及监测措施。
Juhu Road station of Changzhou Metro Line 1 is a monolithic reinforced concrete structure with single column and double span, which is constructed by open cut method. The No. 3 entrance is an underground frame structure. Now it is planned to build a new connecting port project between Juhu Road Station and Wujin Wanda Plaza, to establish a three-dimensional numerical model including the passageway, station structure and affiliated structure, to analyze the displacement of the new municipal passageway on the existing station structure and affiliated engineering. The research results show that the total displacement of the station is 5.147mm, the maximum vertical displacement of the entrance is about 7.442mm, and the maximum horizontal displacement is 1.548mm, all of which meet the requirements of the control index. In the excavation stage, the impact on the existing structure is most remarkable, so it is necessary to strengthen related protection and monitoring measures during construction.
