大跨刚构桥施工控制研究

摘要

随着桥梁跨度的增大，悬臂施工已经成为现代大跨度桥梁建造的主要施工方法。对采用悬臂浇筑施工的桥梁。为确保桥梁结构的合拢精度、成桥线形、内力和运营一定时间后能达到设计所要求的标高。施工控制问题在设计和施工中的作用变得越来越重要。为了形成一套简便可行的施工控制方法。文章以野芷湖大桥为背景。对大跨度连续刚构桥施工控制技术进行了研究。%With the augment of bridge span, cantilever construction has already become the main construction method in long- span bridge construction. Meanwhile, to the bridges built by cantilever construction method, in order to ensure the structural joining accuracy, the alignment and the internal force of finished bridges, and the final meeting elevation to the design requirement after using a certain period, construction control has also became more and more important in design and construction. In order to establish an easy and feasible construction method, took Yezhihu Bridge as the example to study bridge construction control of long span continuous prestressed rigid frame bridges.
