摘要
高速公路桥梁施工涉及面广、作业种类多、作业危险性大,通过合理划分评价单元,采用合适的评价方法,分析不同作业的安全风险,可以控制安全风险,避免潜在事故发生。以预制梁安装作业和悬臂现浇箱梁作业为例,通过传统的LEC法和改进的LEC法分别进行安全评价,阐述了两种方法的区别和改进的LEC法在高速公路桥梁施工中的优势。
The bridge construction of highway is a complicated process,covering a wide range,and having many kinds of workflow. Therefore,there are many risks. We can control the security risks,and avoid potential accidents through dividing reasonable evaluation unit,and adopting appropriate evaluation method,and analyzing security risks in different assignments. This paper is based on precast beam installation operation and cantilever cast-in-place box girder. It indicates that the difference of the two methods and the advantage of the improved LEC method in bridge construction of highway by using traditional LEC method respectively and improved LEC method for safety assessment.
