既有航道桥梁船舶撞击风险评估及抗撞性能分析

Risk Assessment of Ship Collision & Analysis of Anti-Collision Performance on Existing Waterway Bridges

以上海市一座既有高航道桥船舶撞击风险及抗撞性能评估为例,建立既有航道桥梁船舶撞击风险评估和抗撞性能分析方法框架,包括船舶撞击风险隐患识别和综合评估研究。风险隐患识别研究包括桥梁航标校验、通航净空尺度复核以及新老抗撞性能标准的对比;综合评估研究包括通航水域通航安全风险分析和结构抗撞性能分析。研究为类似桥梁的评估分析提供参考。

Taking the ship collision risk and anti-collision performance evaluation of an existing high channel bridge in Shanghai as an example,the method framework of ship collision risk evaluation and anti-collision performance analysis of existing channel bridge is established,including the identification and comprehensive evaluation of hidden dangers of ship collision risk.The research on risk identification includes bridge navigation mark verification.navigation clearance scale review and the comparison of new and old anti-collision performance standards;the comprehensive assessment study includes navigation safety risk analysis and structural anticollision performance analysis in navigable waters.The study provides a reference for the evaluation and analysis of similar bridges.
