【摘要】：摘要：随着经济的快速发展,近年来我国桥梁事业也蓬勃发展。但是随着交通量的增大,以及各种自然因素和人为因素的影响,桥梁的安全性越来越受到人们的重视。因此,有必要对近几十年发生的桥梁安全事故进行统计分析,从而找出引起桥梁安全事故的主要原因,为避免同类桥梁安全事故再次发生起到积极的作用。本文通过收集国内外近40年的611起桥梁安全事故,对其进行归纳总结,从而得出引起桥梁安全事故的主要原因。本文具体包括以下几方面内容： (1)对安全理论进行简介并且对桥梁安全事故进行系统的分类； (2)列举自然因素引起的国内外桥梁安全事故,包括地震、洪水、泥石流、大风等自然灾害对桥梁的破坏； (3)列举人为因素引起的国内外桥梁安全事故,包括设计因素、施工因素、运营管理因素、碰撞因素(船撞和车撞)等人为因素对桥梁的破坏； (4)对收集的国内外桥梁安全事故进行深度调查和分析,主要包括桥梁安全事故的基本原因、详细原因的统计分析,不同桥型和不同材料的桥梁安全事故破坏程度的统计分析,不同主要原因(施工事故、碰撞事故、水利事故以及过载事故)造成的桥梁破坏程度的统计分析等。最后,总结出引起桥梁安全事故的主要原因,并有针对性地提出一些有益的安全评估措施和建议。
[Abstract]:Absrtact: with the rapid development of economy, China's bridge industry is booming in recent years. However, with the increase of traffic volume and the influence of various natural and human factors, people pay more and more attention to the safety of bridges. Therefore, it is necessary to make statistical analysis of bridge safety accidents in recent decades, so as to find out the main causes of bridge safety accidents and play a positive role in avoiding similar bridge safety accidents. Through collecting 611 bridge safety accidents in recent 40 years at home and abroad, this paper sums up and summarizes them, and obtains the main causes of bridge safety accidents. This paper includes the following aspects: (1) brief introduction of safety theory and systematic classification of bridge safety accidents; (2) enumeration of bridge safety accidents at home and abroad caused by natural factors, including earthquakes, Damage to bridges caused by natural disasters such as flood, debris flow, gale, etc. (3) enumerating the safety accidents of bridges at home and abroad caused by human factors, including design factors, construction factors, operational management factors, (4) the deep investigation and analysis of bridge safety accidents collected at home and abroad, including the basic causes of bridge safety accidents, Statistical analysis of the detailed causes, statistical analysis of the damage degree of the bridge safety accidents of different bridge types and different materials, and different main causes (construction accidents, collision accidents, etc.) Statistical analysis of bridge damage caused by water conservancy accident and overload accident etc. Finally, the main causes of bridge safety accidents are summarized, and some useful safety assessment measures and suggestions are put forward.
