最近几天，深圳赛格大厦晃动事件引发公众关注。

 

The 356-meter-tall SEG Plaza¹ in Shenzhen first began shaking on Tuesday afternoon. All those inside were evacuated² within 90 minutes, local authorities said.

5月18日下午，356米高的深圳赛格大厦第一次发生晃动。当地政府表示，楼内所有人员在90分钟内全部疏散撤离。

 

监测数据未显示异常情况

 

From 9 pm on Tuesday to 3 pm on Wednesday, a number of professional organizations closely monitored the skyscraper's vibration³, tilt⁴ and subsidence. The three indicators⁵ were far below levels that would prompt concerns, and data from the monitoring did not reveal any abnormalities, the city's housing and urban-rural development bureau said in a statement.

5月18日晚上21时至19日下午15时，多家专业机构对赛格大厦的振动、倾斜、沉降等情况进行实时监测。深圳市住建局表示，该三项指标均远远小于规范允许值，监测数据未显示异常情况。

 

A preliminary investigation⁶ had found the wobbling was vertical⁷ rather than horizontal and that it was caused by a combination of winds, two underground rail lines under the building and the stretch of the steel caused by the rising temperature.

初步调查结果显示，深圳赛格大厦系上下震颤而不是左右摆动，造成震颤的原因是多种因素耦合，包括风的影响，两条地铁从楼下经过以及近期气温升高对钢结构产生的影响。

 

5月21日，一份落款为深圳赛格集团有限公司的通知显示：为确保赛格大厦检测工作顺利进行，不受外界干扰，经赛格集团研究决定，自5月21日零时起，暂停所有业主、商户、租户进出赛格大厦写字楼和电子市场（all business owners, vendors⁸ and tenants⁹ will be denied access to the plaza），待相关检测工作完成后再有序开放，有关事宜另行通知。

 

深圳市将根据楼体结构排查情况，研判大厦恢复开放时间。鉴于该大厦未安装阻尼器（tuned¹⁰ mass damper），专家建议，下一步可以考虑安装阻尼器以提高防风防震能力和舒适度。
