A Study on the Geometry Control of the Precast Segmental Bridges and the Fabrication of Precast Segments

프리캐스트 세그멘탈 교량의 선형관리와 세그멘트 제작에 관한 연구

In this study, an investigation on the geometry control of the precast segmental method(PSM) was performed and GEOCON was developed. It is an interactive software to control the 3-dimensional geometry of precast segmental bridges during the construction progress. Specially, this paper emphasized that the fabrication stage of the precast segment is the most important for the geometry control in the PSM and also descussed about some problems which can be overlooked in developing and using the geometry control softwares by explaining the GEOCON's characteristics. GEOCON was successfully applied to the surrounding road of Pusan harbor.
