佛山市南海区地铁金融城项目振动控制研究

Research on the Vibration Control of Metro Financial City Project in Foshan City

以佛山市南海区地铁金融城项目为例,分析地铁线路上盖建筑的振动控制设计措施。项目实施前,先对既有类似项目进行了调研和测试,以指导相应的减振措施。项目裙楼施工完成后,对地铁振动进行了现场实测,并通过采集的数据进行数值分析。结果证明:采用浮置板轨道、建筑结构采取脱开设计等振动控制措施是合理的。

A metro project in Nanhai District of Foshan City is taken as the example to analyse the vibration control measures in the design of metro upper cover buildings.Before the construction,many similar projects are investigated and tested to guide the corresponding vibration control measures.After the completion of project podium construction,the metro vibration is measured on the spot and the filed test data are collected for numerical simulation.Results show that the vibration control measures by adopting floating slab track and separated design of the upper building structure are reasonable.
