INCREMENTALLY LAUNCHED CONCRETE BRIDGES. SINO-BRITISH HIGHWAYS AND URBAN TRAFFIC CONFERENCE. PAPERS PRESENTED AT THE CONFERENCE HELD IN BEIJING 17TH-22ND NOVEMBER 1986
This paper describes the main features of the incremental launching method for building bridges and elevated highway structures; the concept of incremental launching was derived from that of the Bailey bridge. In the incremental launching method, the bridge superstructure is constructed in segments, which use stationary formwork in a fabrication area normally located behind an abutment. Segments are added one at a time, with the formwork available for constructing the following segment at any stage; this process is repeated until the full length of deck is in its final position. The advantages and disadvantages of this approach are discussed; although it has become progressively more practicable during recent years, bridge geometry is the area where its limitations are most significant. The chief limitations involve geometry, working space, and span. Selected design aspects and recent developments considered include: (1) general suitability; (2) three-span bridges; (3) girder cross section; (4) design of girder for launching; (5) computer-aided design. Selected construction aspects considered include: (1) fabrication area and production cycle; (2) launching equipment; (3) control of launch forces. (TRRL)
