| Abstract: | The finite element model which analyzes the stress of beam section in each construction step is established through stimulating the construction process of Ehuang Highway Bridge over Yangtze River. The transverse stress increasing regulation of beam section in different stage is discussed, and some possible strain methods of prestressing steel wires in crossing beam are analyzed and compared with each other, then the rational sequence of straining prestressing steel wires is brought forward. |

| Keywords: | finite element model transverse stress sequence of straining prestressing steel wire |
