本文从最近国内多座桥梁倾覆破坏的事例出发,指出了目前在桥梁设计中的不足之处,并分析了桥梁结构破坏机理上的原因。同时运用桥梁倾覆安全风险评估的方法,提出了设计中应该采取的防止倾覆的安全措施。文中指明了目前桥梁发生倾覆破坏,并非偶然事件,还存在一定等级的风险因素。 Based on the recent cases of overturning over bridges in China, this paper points out the shortcomings in current bridge design and analyzes the causes of the failure mechanism of bridge structures. At the same time, by using the method of safety risk assessment of bridge overturning, the safety measures of preventing overturning should be put forward. The article pointed out that the current tipping over the bridge damage is not an accident, there are still a certain level of risk factors.
