摘要
本文提出桥梁大跨径顶推墩上设撑架不设临时墩的合理方法,并对撑架的结构形式和支撑方法进行了研究.最后结合试验桥提出若干技术问题.
The paper presents a reasonal incremental launching technique for larger-span (span over 70m) bridges with cantilevered bracing frames on piers,instead of setting up a temporary support between two piers. The several types of bracing frame are compared structurally and internal forces in the frame are studied accordingly. Finally some key problems in the construction are discussed with information from an experimental bridge of Qiudong.
