新建张唐铁路太师庄特大桥54.5m简支拱支架设计与施工

The Design and Construction of 54. 5-metre Simply Supported Arch Framework in the Newly-built Taishizhuang Bridge of Zhangjiakou-Tangshan Railway

以新建铁路张家口到唐山铁路太师庄特大桥54.5m简支拱工程施工为例,对该简支拱支架设计进行了详细的阐述,并通过数值计算对支架结构进行了检算,对主梁的支架法施工进行了具体的讲述,结合施工现场的实际施工情况,说明该支架设计和主梁施工方案满足施工现场的要求,该计算成果满足施工安全、稳定的要求.

Taking the construction of 54.5-metre Simply Supported Arch Framework in the Newly-built Taishizhuang Bridge of Zhangjiakou-Tangshan Railway as an example, this paper expounds the design of simply supported arch framework, and checks the index of the framework with detailed numerical calculation. With reference to the actual situation of its construction, the design of arch framework and construction scheme of main girder meet the requirements of the construction site, and the results of calculation meet the requirements of construction safety and stability.
