英文摘要：

Regarding the vehicle and the bridge as a combined vibration system and usmg research metnoas of bridge structure dynamics and vehicle dynamics, a vehicle/bridge interaction model of Wuhan Tianxingzhou Yangtze-River Bridge was established. Based on the reasonable train runability evaluations, the train running safety and passenger riding comfort with freight trains and high-speed trains across the bridge were especially studied. The applicability of long-span rail-cum-road cable-stayed bridge for freight trains and high-speed trains mixed running was investigated.
