摘要：随着社会的经济发展，交通也越发的便捷 。而公路桥梁也成为交通运输中必不可少的部分。近些年来，路桥施工的安全事故频发，造成了巨大的人员伤亡和经济损失，所以路桥施工风险的识别，分析、研究尤为重要。通过目前常用的研究方法对路桥施工进行评价，提出措施，预防控制可能发生的危险。

本文以一段模拟路桥的施工作为评价模型，采用指标体系法，层次分析法，集对分析法对路桥施工进行评价。即识别危险源，分析危险源指标层确定权重，对路桥施工公司的安全管理进行评价，制定安全措施。通过实际案例反映路桥施工安全风险的识别，评价，防控必不可少。阐述国内外对于安全评价的成果，分析了安全评价在路桥施工中的重要地位。总结各个工段的步骤流程，分析其风险源以及产生的因素。通过影响各风险源的因素构建模型，运用层次分析法、集对分析法对路桥施工进行评价。通过评价内容，相应制定整改措施进行预防控制。

The Risk analysis and The control of construction safety in the Highway Bridge

Abstract：With the economic development of the society, the traffic is more and more convenient. Highway bridges have also become an essential part of transportation. In recent years, Highway Bridge construction safety accidents, resulting in huge casualties and economic losses, so the identification, analysis, and research of construction risk in Highway Bridge is particularly important. Through the current commonly used research methods, Highway Bridge construction is evaluated, and measures are put forward to prevent and control possible risks.

In this paper, the construction of a simulated Highway Bridge is taken as an evaluation model. The index system method, analytic hierarchy process and set pair analysis method are adopted to evaluate the Highway Bridge construction. That is to identify hazard sources, analyze the weight of hazard sources, determine the weight of the risk sources, evaluate the safety management of Highway Bridge construction companies, and formulate safety measuresthrough actual cases, it is necessary to identify, evaluate and prevent construction safety risks in Highway Bridge. This paper expounds the achievements of safety evaluation both at home and abroad, and analyzes the important position of safety evaluation in the construction of Highway Bridge.  summarize the steps of each section, analyze the risk sources and factors.build the model through the factors of various risk sources, and use the analytic hierarchy process and set pair analysis to evaluate the construction of Highway Bridge.through the evaluation of content, the corresponding corrective measures should be formulated for prevention and control.

Key words: highway bridge construction; analytic hierarchy process; set pair analysis; risk control;
