结合实例对轨道交通高架桥抗震设计的探讨
|
摘要
本文结合北京地铁海山线的结构设计,对轨道交通高架桥抗震设计中普遍存在的概念设计、钢轨影响效应、桩土相互作用以及墩柱截面合理配筋等问题进行分析和探讨。提出在抗震设计中概念设计应先行,明确钢轨对桥跨抗震性能的影响效应,综合比较桩土相互作用的模拟计算方法和延性墩柱截面合理计算方法,提出适用于轨道交通高架桥梁的抗震设计方案,为今后同类桥梁的设计实践工作提供参考。
Several general problems of mass transit viaduct design were analyzed and discussed in this paper,such as ordinary seismic concept design,restraint effect of steel-rails on viaducts,pile-soil interaction and reasonable reinforcement design of piers,combined with engineering practice on Beijing metro Haishan line.Seismic concept design was suggested to be put forward when begin seismic design.Effect of steel-rail to the seismic behavior of viaducts was made clearly.Through the comparison of simulation calculation methods on pile-soil interaction and reasonable calculation methods of ductile pier section,a seismic design plan of rail transit viaduct was proposed.It is hoped to bring valuable references for design and construction of similar structures.
