On the principle of calculus variation, the roadway response to moving vehicle, in which the roadway is assumed to be rigid pavement lying on Winker foundation, is analyzed. 利用变分原理,研究分析了在车辆运动作用下,弹性W地基上的刚性路面的动力反应。
In this paper, with polygon line hypothesis of τ-u relationship of horizontal restrained condition of foundation, and winker hypothesis of vertical restrained condition of foundation, a new analytical method to calculate thermal stress of mass concrete structure on foundation with biconditional restriction is presented. 本文考虑地基对板的双向约束以及非均匀受力的计算模型,竖向约束采用文克尔假定,水平约束采用折线假定,推导出有关地基上大体积混凝土板的温度应力计算的解析方法。
