广泛适用性桥梁工程风险评估综合指标体系研究

Comprehensive Index System for Widely Applicable Risk Assessment of Bridge Engineering

针对桥梁风险评估指标体系在工程实践中应用的局限性和不一致性问题开展研究。通过国内外文献调研,指出全局性的桥梁风险评估指标体系的构建是现有桥梁风险评估工作的迫切需求。以现有研究为基础,通过构建桥梁综合风险指标识别流程,对桥梁风险评估底层指标进行了系统的筛查分析,提出了具有广泛适用性的多层次、多维度、综合性的桥梁风险指标体系。研究结果表明:建立的指标体系可以补足桥梁风险评估基础性研究工作,为今后桥梁风险评估在具体工程实践中的应用提供统一的指标体系参照。

This research focuses on the localization and inconsistency of bridge risk assessment index system in engineering practice.The classification methods and application status for the widely used risk index system are also summarized.The review shows that the con-struction of a global bridge risk assessment index system is an urgent need for current bridge risk assessment.Thus,a comprehensive risk identification process for bridge engineering is established based on the existing research.Then a multi-level,multi-dimensional and comprehensive risk index system is proposed by systematic screening analysis of the bottom indicators for the bridge engineering.The results show that the proposed global index system strengthens the fundamental research works on the bridge risk assessment and provide a unified index system reference for the application of bridge risk assessment in the future engineering practice.
