摘要
Abstract
The screw-thread steel bar is often used for the connection between launching nose and main girder in typical incremental launching process. Because the thickness of the web plate is thin and the launching nose is not matched with the height of the girder, it is difficult to meet the needs of incremental launching construction by using conventional screw-thread steel bar connection method. To solve this problem, this paper presents a new method of connection by combining shear force distribution beam with horizontal screw-thread steel bars. The practice proves that the connection is simple and applicable. The successful application provides good and meaningful references for the launching nose connection of other similar flyovers ( crossing over railway and highway) .关键词
