| 摘 要： | 本文从动力学的角度出发,应用有限元方法计算了铺装层在不同的模量、厚度和车速条件下的动力响应的变化规律,分析了单轮荷载和双轮荷载两种荷载型式对动力响应的影响,并与以往的静力计算结果作出了比较.分析表明,采用动力计算模式比静力更为不利,在常温及高温条件下,铺装层初始设计厚度较薄时,采用双轮荷载作用形式比单轮更偏于安全,研究成果可为铺装层材料和结构设计提供理论依据.

| Abstract: | The dynamic response of deck pavement under different effecting parameters was analyzed with FEM, and the results were compared with the static results. Analysis results show that the dynamic response is more unfavorable compared with the static one. Under the normal and high temperature environment, when the initial design thickness of pavement is thinner, the dynamic response of pavement under double-wheel load is more safety compared with that under single-wheel load. The research results provide a theoretical basis for the analysis of the material and structure of deck pavement. |
