基于Midas Civil的现浇箱梁桥面铺装模拟方法研究

The study of simulation method of deck pavement of cast-in-place box beam bridge based on Midas Civil

桥面铺装层对桥梁主梁结构受力有着复杂的影响,现有的研究多采用ANSYS模拟桥面铺装,模拟方法复杂繁琐,不利于工程应用,而实际工程计算中多将铺装以荷载模拟,"保守"的分析对结构主体的影响。Midas是较为成熟准确且界面友好的有限元计算软件,在桥梁工程中得到了非常广泛的应用。结合某工程实例,基于Midas有限元软件,针对现浇箱梁的桥面铺装提出了五种模拟方法,通过计算分析,互相参照对比后,得到适合于此类桥型的基于Midas的桥面铺装模拟方法,为以后的类似工程建模提供参考。

The bridge deck pavement has complex effects on the stress of main bridge structure. Current researches use ANSYS to simulate deck pavement which is complicated and time - eonsmning, and not appropriate for engineering application. The deck pavement is mostly simulated as load to analyze its impaetion on strueture unsafely. Midas Civil is a mature and accurate finite element software which is widely spread in bridge engineering. Five simulation methods are raised up aiming at cast - in - place box beam bridge based on Midas Civil, combined with a living bridge example. By calculation and analyzing appropriate deck pavement simulation method is found to provide reference for similar engineering.
