大跨径钢桥面铺装层动力响应研究
, PP. 68-72
Keywords: 桥梁工程,钢桥面铺装,有限元,动力响应
Abstract:
为了揭示钢桥梁桥面沥青混凝土铺装的实际受力特性,利用有限元方法对大跨径正交异性钢桥面铺装层的瞬态动力学响应进行了分析和计算.在不同层间接触条件时,对铺装层静力和动力响应计算结果分析的基础上,着重对完全光滑条件下不同加载周期、不同铺装层模量以及不同铺装层厚度等对铺装层动力响应的影响进行了探讨.结果表明,完全光滑和完全连续接触条件下铺装层的动力响应截然不同,完全光滑时铺装层的最大拉应力为完全连续时的近10倍;加载周期及铺装层模量对铺装层的动力响应影响不显著;铺装层厚度对铺装层动力响应影响较大,当铺装层与钢桥面板之间完全滑动时,6cm左右的铺装层厚度是最不利的.与静力学计算结果相比,动力计算结果更加接近实际情况.
