桥梁通航安全影响分析探讨

Analysis and Discussion Bridge Navigation Safety

以潼南东升大桥为例进行通航安全影响分析探讨,结果表明:桥梁建设前,必须根据跨江航道等级对桥梁通航安全进行分析论证,通航安全受多因素影响,需综合考虑桥梁建设对河床冲淤、桥区航道维护、助导航设施、交通组织、通航秩序、水域船撞风险的影响。

Taking Tongnan Dongsheng Bridge as an example to analysis and discuss the influence of navigation safety.The results show that:before bridge construction,bridge navigation safety must be analyzed and demonstrated according to the grade of cross-river channel.Navigation safety is affected by multiple factors,and it is necessary to comprehensively consider the influence of bridge construction on river bed erosion and sedimentation,channel maintenance in bridge area,navigational AIDS,traffic organization,navigation order,and ship collision risk in water area.
