1、摘 要近年来我国正在进行大规模的基本建设，期间有很多桥梁已经开始建设。在建设的同时，我国逐渐加大了安全生产工作的力度，尽量通过管理和技术方面的研究来预防安全事故的发生。由于拱桥施工工艺复杂、技术含量高、施工难度大、施工队伍安全意识薄弱等因素的影响，拱桥施工事故发生率一直居高不下。可见对拱桥施工的安全进行研究对减少事故的发生率和人员的伤亡率具有重要意义。本文通过查阅国内外拱桥施工安全方面的相关文献，了解拱桥施工方法和特点、常见施工事故及其预防措施等方面的内容，运用安全检查表法对拱桥施工进行安全分析评价。本文首先根据拱桥施工工程的具体情况选择合适的安全检查表，运用法律法规逐条对检查项目进行检查分析
2、，然后根据结果分析，提出改进措施及建议，从而预防事故的发生。关键词：拱桥施工 安全检查表分析 安全 ABSTRACTIn recent years, many bridges have started building when China is in large-scale infrastructure.As the construction our country gradually raises the power of safety produce work,as far as possible preventing safety accident by manage and tech

So researches on the arch bridge constr
4、uction safety is very important ,which not only can reduce the frequency of accidents, but also can reduce the casualty rate.Through searching for domestic and abroad arch bridge construction safety literature, understanding the construction method and construction feature of arch bridge, the common
5、 accidents and preventing measure of them, safety check analysis was be used in arch bridge construction of safety analyse evaluation. Firstly, according to the situation of the arch bridge construction project choosed the appropriate safety checklist,using legal regulations analysed the examination
6、 items oen by one,and then according to the situation of the arch bridge construction project,the safety index system structure was established, finally, according to the results of the analysis, corrective measures and suggestions were proposed to prevent accidents.Key words:arch bridge constructio
