| 摘 要： | 主要研究了采用装配式公路钢桥桁架(通常称为贝雷架)做为支架进行连续梁桥现浇箱梁混凝土的施工方法;研究了跨河施工支架的技术方案,特别是施工支架在桥墩上的刚性斜撑,同时结合现场试验研究了施工支架的分析计算方法及变形。研究表明,采用装配式公路钢桥桁架解决跨河预应力混凝土连续梁现浇混凝土施工支架问题是有效的。

| Abstract: | This paper mainly makes the research of construction method for cast-in-situ concrete box girder of continuous girder bridge,using assembled highway bridge steel truss(often known as Bailey Truss) as the falsework,technical schemes for the falsework erected over river,particularly the rigid slant supports of the falsework on piers,and analysis,calculation methods and deformation of the falsework in accordance with the related tests in field.The results of the research indicate that the assembled highway bridge steel truss is an effective means to resolve the common problems of falsework over river for construction of cast-in-situ prestressed concrete continuous girders. |
