Research on the Precision Control Technology of Short - line Segmental Prefabricated Assembly Bridge

Abstract

Abstract Short-line prestressed assembly bridge construction method has been widespread used for more than 10 years in China, unlike the “wysiwyg” cast-in-place beam, prefabrication and assembling construction process control is more important, especially for the virtual segment assembly. Due to the short line method commonly used in the large-scale bridge project, it is necessary to research intensive construction control, and improve the level of short line method. This article studied in two ways: the precast assembling error processing and precision control based on parametric analysis of the structure deformation.
