| 摘 要： | 东北电网电力调度交易中心为坐落于大底盘地下室上的20层主楼和4层辅楼,主楼、辅楼之间由阳光大厅和连廊连接,抗震设防类别分别为乙类和甲类。地基主要受力层范围内既有杂填土又局部存在软弱下卧夹层,采用调整基础底面积和不同的地基处理方法来满足上部结构对地基承载力和变形的要求。地下室长198.8m,宽143.0m,采用补偿收缩混凝土结构自防水和无缝设计技术,实现地下室无缝施工。为避免主楼、辅楼与大厅屋盖之间的相互影响,阳光大厅屋盖和连廊支座采用隔震橡胶支座,分别进行7度小震、中震和大震作用下的整体计算分析和大震作用下的弹塑性变形验算,并对关键结构构件采用型钢混凝土构件或钢桁架,实现抗震设计的性能目标。

| Abstract: | The electric power dispatching and trade center of Northeast Grid consists of main building and auxiliary building.The seismic requirement is B level for main building and A level for auxiliary building.Filling soil is mixed with underlying soft soil to form the main bearing layers of subsoil,whose capacity and deformation are satisfied by adjusting foundation area and ground treatment method.Shrinkage compensating concrete and non-joint design technology were adopted for mass basement whose dimension is 19... |
