Study on Bridge Deck Link Slabs of Simply Supported Girder Bridges
Accordingto the status of seriously early disease, the diseases investigation and causesanalysis were performed on bridge deck link slabs. The results show thattransverse cracks and pot holes are the main forms of diseases of bridge decklink slabs. The main reason of diseases for bridge deck link slabs is the lightstructure, mechanical complex, unclearly to the performance under force, anddifficult to guarantee the quality of construction. According to the causes ofdiseases, the linear elastic analysis was performed on bridge deck link slabunder loading. The formula of maximum tensile stress of concrete in bridge decklink slab is derived. The main factors affecting the internal force of bridgedeck link slab were analyzed. The suitable structure of bridge deck link slabsis proposed.
