公跨铁连续梁满堂支架的设计及检算

Design and Calculation of Highway Overpass Railway Continuous Beam Trestle

支架施工是指在支架上安装模板,绑扎钢筋骨架,并在现场浇筑混凝土的施工方法,由于其施工方法相对简便,造价相对低廉,因此非常适用于整体结构,尤其是在连续梁结构中得到广泛应用。结合新建武汉至黄冈城际铁路公跨铁立交桥连续梁满堂支架设计、施工过程,介绍带门洞满堂支架的设计及检算。

Trestle construction refers to the construction of the template installation on the bracket,binding of steel bar skeleton,and the construction method of cast-in-situ concrete.Because of its relatively simple construction method,and relatively low cost,it is very suitable for the whole structure,and it has been widely used especially in continuous beam structure.In this paper,based on the new Wuhan to Huanggang inter-city railway highway overpass railway overpass continuous girders,design,construction process,this paper introduces the design and checking calculation of full space support with a door trestle.
