Incremental Launching of Final Composite Bridge Deck

摘要

The paper explains new technological processes, static analysis, structural details and monitoring during launching. The bridge deck cast in workshop is not deformed and all cycle operations go on in one location. The structure was constructed with high accuracy. The erection speed was 18 m per week. A special balanced static indeterminate system was developed to decrease the influence of horizontal friction forces on flexible piers and abutments and to ensure the stability of temporary piers during launching.
