| 摘 要： | 桥梁运营期的船撞风险已逐渐成为桥梁工程面临的尖锐问题之一,因此对桥梁运营期的船撞风险进行风险评估具有重要意义.结合崇启通道工程,运用AASHTO指南方法对崇启大桥运营期各桥墩年船撞概率及年倒塌概率进行计算,对崇启大桥运营期的船撞风险进行了评估.崇启大桥运营期总体船撞风险评估等级为三级,属于中等风险水平.需要工程建设参与方以及运营管理方引起足够重视,采取防范、监控措施.

| Abstract: | Ship collision risk during the operation period of a bridge is gradually becoming a serious problem.So it has the important significance to execute the evaluation of the ship collision risk during operation period of a bridge.Using the method of AASHTO guide,the calculation of the ship collision probability per year has been executed and the failure probability per year of the piers of Chongqi Bridge was provided in details.The results show that the overall level for ship collision risk of Chongqi Bridge du... |
