混合梁刚构桥悬浇挂篮-桥面起重机一体化设计

Integrated Design of Cantilever-cast Basket-deck Crane of Mixed Beam Rigid Frame Bridge

近几年,我国高速公路、高铁施工持续快速发展,混合梁连续刚构桥施工工艺逐渐成熟,桥梁也向大跨径、大吨位发展。以安海湾特大桥为例,对特大跨径的混合梁连续刚构桥施工重难点进行了研究,设计了一种可同时满足悬臂挂篮施工和钢箱梁吊装等多种施工工况的通用型模数式挂篮-桥面起重机桁架。该通用型模数式承重桁架的成功应用,可为类似工程提供借鉴。

In recent years,the construction of highway and high-speed railway in China has been developing rapidly,and the construction technology of continuous rigid frame bridge with mixed beam has gradually matured.Taking Anhaiwan Bridge as an example,this paper studies the construction difficulties of continuous rigid frame bridge with mixed beam with large span.The successful application of the universal modular bearing truss can provide reference for similar projects.
