Structure Study of Arch Bridge with a Span of 600m Part II: Measures to Improve Mechanical Performance

摘要

Take the trail design of arch bridge with a span of 600m in Part I as the research object, this paper proposes the existing critical problems of the structure, including structure's static performance, stable problem and dynamic problem. Measures to improve structure's mechanical performance have been proposed in the respects of structure system, component system and design parameters so as to improve the economy and safety of the structure.
