摘要
根据北京西直门内部环路点支承异型弯板桥的实际结构特点,以 Midas/Civil大型结构分析有限元软件为工具,对空间的弯、坡、斜实体板桥进行了计算分析,提出板桥设计断面的确认及支座模拟参数,并提出了人行车道面、沉降组荷载工况、包络工况的设计概念。
The paper makes the calculation analysis of the space bend, slope and skewed solid slab bridges taking as the tool of Midas/Civil large type structural analysis finite element software in accordance with the actual structural characteristics of point bearing deformed bend slab bridge on ring road of Beijing Xizhimen inside. It also puts forward the confirmation of the design section of the slab bridge as well as the simulated parameters of bearing support. At the same time, it puts forward the design conception of pedestrian lane surface, settlement group loading working condition and envelope working condition.
