关于公路桥梁提高抗震能力的设计思考
|
摘要
近些年来,世界范围内地震自然灾害频频发生,人们在建筑设计时更多地关注建筑工程的抗震能力。桥梁梁板连续系统就是一种在发生强等级的大地震时,防止桥梁发生落梁现象的安全防护性装置。文章结合我国公路桥梁工程设计特点和防震等级要求,提出采用梁板连续系统提高桥梁抗震能力的设计思考。
In recent years, the worldwide earthquake disasters occurred frequently, people pay more attention to the seismic capacity of buildings in the architectural design. Bridge beam slab continuous system is a kind of preventing the occurrence of safety protection device for bridge girder falling phenolmenon in the high level of large earthquakes. Combining with the design features of road and bridge engineering earthquake level requirements in China, this paper puts forward design thinking of beam slab continuous system to enhance the bridge seismic capacity.
