| Abstract: | The superstructures of the bridges on Meihe Expressway and Jingyin Expressway are the pre-tensioning pre-stressed concrete hollow slabs which are centralized to prefabricate in the prefabrication fields.Taking the pre-stressing tensioning construction of the hollow slabs for the above two expressways as the practical example,starting with the bearing principle of the steel strand cable before and after tensioning,the article discusses the pre-stressing tensioning construction technology. |
