摘要
为做好桥梁安全风险评估,实现对众多风险源的有效预防和控制,选择具有代表性的重要因素,建立了西北干寒地区在役桥梁安全风险评价体系,基于熵权法对其进行安全风险权重计算,对施工及维护进行有效的安全评估。分析了西北干寒地区在役桥梁的长期性能,合理评估在役桥梁的安全风险,为后续桥梁安全风险防范提供了参考依据。
In order to do well in safety risk assessment of bridges,and achieve effective prevention and control of many risk sources,the study selects representative important factors,establishes the safety risk evaluation system of bridges in service in northwest dry and cold region,calculates safety risk weights based on entropy weight method,and does effective safety evaluation on construction and maintenance.Then the study analyzes the long-term performance of bridges in service in northwest dry and cold region,and rationally evaluates the safety risk of the bridges in service,to provide reference for the bridge safety risk prevention.
