| Abstract: | This paper takes Jiubao Bridge for example to make a comparative analysis of the walking-style horizontal pushing technology and the traditional drag-type construction technology. The innovative use of ＂walking-style horizontal pushing technology＂ to install three spans with arches in one process makes a breakthrough of the traditional drag-type construction technology and ensures the quality of the bridge construction and the completion of Jiubao Bridge within the specified construction period. |
