Dynamic Load Model Test Study on Steel Bridge Deck Surface Deformation of Pearl River Huangpu Bridge

摘要

Bridge Deck is a technical difficulty of the construction of large span steel bridge, the using of steel bridge deck that the steel bridge by the force and deformation under the dynamic conditions for bridge deck pavement performance evaluation is a hot pilot study. In this paper, combine Guangzhou Pearl River Huangpu Bridge steel box girder bridge layer technology and design research projects, observation and analysis the United States and Japan of two kinds epoxy asphalt for accelerated loading test by accelerated loading model test equipment. Finally, come to fatigue destruction development model of Long Span Steel Bridge Deck surface, as well as Pavement Materials and deformation of interrelatedness, ultimately, provide scientific guidance recommendations for large span steel bridge deck.
