摘要
利用有限元分析海东市某独塔双索面组合梁斜拉桥的双层钢桥面在实际荷载作用下铺装效果,通过控制荷载加载点,对铺装层弹性模量、厚度、温差对应力和弯沉的影响进行参数化分析,最终得到适宜于该桥的铺装层结构性参数。为后续寒区相关工程技术提供借鉴。
The paving effect under the actual load of double-layer steel deck pavement of a single-tower,double-cable-plane composite beam cable-stayed bridge in Haidong City is analyzed by finite element.By controlling the load loading point,the influence of the elastic modulus,thickness and temperature difference of the pavement layer on the stress and deflection are analyzed parametrically.Finally,the structural parameters of the pavement layer suitable for the bridge are obtained,these provide reference for follow-up related engineering technologies in cold regions.
