| Abstract: | This paper takes Songhua River Bridge construction as an example, based on the geographical environment and climate conditions of this project, analyzes in detail the large cantilever stability of this bridge under the wind load and offset load in winter, puts forward several load combination loading methods, and introduces the safety measures taken for this bridge. Finally, conclusions are drawn through an comparative analysis of the monitoring data of the bridge at the site. |
