Beijing News (Reporter Sun Zhao Liu Mingyang) Today (May 5), the rise and fall of the Humen Bridge in Dongguan, Guangdong, has caused concern. Professor Ge Yaojun, a well-known bridge design expert and bridge wind engineering research expert, told the Beijing News that the cause of Humen Bridge's vortex vibration may be related to the construction of the bridge deck, but it will not affect the rigidity of the bridge. Currently, the Humen Bridge has been closed.
The live video showed that the cars on a bridge were driving normally, and the bridge surface undulated and jittered, and the amplitude of the jitter was visible to the naked eye.

According to public information, the Humen Bridge is a large-scale suspension bridge connecting Guangdong Nansha District and Humen Town of Dongguan City in Guangdong Province. It is a large suspension bridge and passed the completion acceptance in 1999.
In this regard, Professor Fang Zheng of the School of Civil Engineering and Architecture of Wuhan University said that the suspension bridge will have a safe range of jitter during the design.
In addition, Professor Ge Yaojun, a well-known bridge design expert and bridge wind engineering research expert, told the Beijing News that the cause of the vortex vibration of the Humen Bridge may be related to the construction of the bridge deck, "This thing changes the shape of the bridge structure. With this thing, it becomes very blunt. "
Ge Yaojun believes that vortex vibration will not affect the rigidity of the bridge, "but people will be uncomfortable at the top, and driving safety will also be affected."
At 22:20 today, a reporter from the Beijing News learned from the Traffic Police Detachment of the Guangzhou Public Security Bureau that at 15:32 today, the traffic police departments of Guangzhou and Dongguan have imposed traffic control on the Humen Bridge, and vehicles passing by have to detour.
