| Abstract: | There are several dozens highway bridges newly built across Tongyu River in the north area of Jiangsu Province. More than a dozen of them are concrete tied arch bridges. During construction, components such as ties, concrete arch ribs and so on were prefabricated in the factory and then the site installation and splicing were carried out according to the certain procedure. Pre-stressing technologies were performed accordingly to form an internally statically-indeterminate and externally statically-determinate concrete tied arch structure. |
