A new Technology for Incremental Launching the Small Curvature Radius Variable Cross-Section Steel Box Girder

Abstract

Abstract. This paper mainly introduces a new technology for incremental launching the small curvature radius variable cross-section steel box girder. To solve the difficulties traditional construction method encountered, new incremental launching method, girder curvature adaptation technology and intelligent surveillance system are researched and developed. By using this technology, launching construction of the small curvature radius variable cross-section steel box girder in urban is practically implemented.
