(华东建筑设计研究院有限公司，上海200002)[摘要]本文介绍了轨道交通十号线吴中路停车场列检二库及其上盖商业楼、办公楼综合开发项目的基础及上部结构设计。本工程具有毗邻地铁站及原有建筑、结构超长、首层楼板高差较大、首层与二层层高相差悬殊、停车列检库与上盖建筑功能不一致等特点。采取基础分期开挖、设置上柱墩减小开挖深度、控制桩基沉降量等措施避免新建建筑对地铁运营和原有建筑正常使用造成影响。设置膨胀加强带减少温度应力的影响；首层楼板高差处设置梁加腋传递水平地震力；二层调节层高和设置设备夹层改善二层上下层刚度比。最后对转换形式、转换位置、转换层以上结构体系进行了比选。[关键词]列检库;上盖建筑;结构设计;膨胀加强带;刚度比;转换形式;转换位置;加腋梁中图分类号：TU318，U231+.3 文献标识码：A 文章编号：1002-848X（2013）S1-0123-06Structural design of topside building on metro garage for train parking and inspectingJiang Kewei(East China Architecture Design & Research Institute Co., Ltd., Shanghai 200002,China)Abstract:Foundation and upper structure design are introduced in this project, including the GarageⅡ of Metro Line 10, commercial buildings, office buildings above the GarageⅡ at Wuzhong Road, Shanghai. The project is near the built metro station and platform, with characteristic such as overlong structure, big elevation difference at the first floor(ground floor), big height difference between the first floor and the second floor, different architectural functions between the GarageⅡ and its topside buildings, etc.To ensure the using of the GarageⅡ and other built parts, many measures are used, such as excavating by stages, setting upper column pier to reduce excavating depth, minimizing pile settlement. Expansion strengthening belts are used to reduce the temperature affect. Haunched beams at the first floor with elevation difference are used to transit horizontal force smoothly. Story height is adjusted and additional MEP interlayer is set to minimize the height difference between the lower two floors. At last, comparisons of transform method, location, and the topside structural type are stated.Keywords:garage for train parking and inspecting; topside building; structure design; expansion strengthening belt; stiffness ratio; transform form; transform location; haunched beam
