Abstrakt:

Mokpo Bridge is a 3-span cable stayed bridge with a steel box girder and a main span of 500m, located in Mokpo city, Korea. Geometry control method based on dimension of structural elements was applied to construct the bridge. The error was wholly controlled from the prefabrication phase of bridge element to the construction phase. During construction, error estimation and correction was done by forecasting analysis through computer model updated in accordance with the situation of the site. The tension forces of stay cables and geometry of the bridge could be controlled by this process within target range during construction and after completion. This paper presents the main features of geometry control method adopted for Mokpo Bridge.
