地铁车辆段上盖建筑高度提升探讨

Discussion on Increasing Building Height of the Metro Depot Superstructure

为提高地铁车辆段上盖物业建设高度,对车辆段及其上盖结构体系进行了研究。对多个案例的计算及分析表明:采用柱端加腋可改善车辆段厂房的抗侧刚度;利用层间隔震技术可解决楼层刚度突变;采用全框支转换结构性能化设计、隔震框支剪力墙结构性能化设计等方法可实现地铁车辆段上盖建筑高度提升。另外证明了在满足地基承载力、变形和稳定性的条件下,不需要刻意增加基础埋深。

The structural systems are studied for the increase in height of the Metro depot superstructure.The trial calculation and analy‐sis of several cases show that:It is proved that adding haunch at the column end can improve the lateral stiffness of the depot workshop building.Using the storey isolation technique will solve the problem of stiffness-extreme soft storey irregularity.Using performance-based seismic design including bottom-frame support structure and isolation for bottom-frame support shear wall etc.will increase the height of the superstructure.In addition,it is proved that there is no need to increase the embedded depth as the bearing capacity,deformation and stabili‐ty of the foundation are fulfilled.
