| 摘 要： | 本文对弹性地基上有垂直与水平方向约束的混凝土结构提出了一种计算温度应力的近似解析方法。通过计算机程序分析出板中温度应力随各种不同参数变化的规律。本文强调软土地基,尤其是上海淤泥质土上基础板的非均匀温度应力,它区别于硬岩地基,因为在硬岩地基上,当板的高跨比较小时,非均匀温度应力可以忽略不计。

| Abstract: | In regard to concrete structures restricted in horizontal and perpendicular directions on elastic base an approximate analytical method used to calculate thermal stresses is presented in this paper. With computer programs it is ana-lysed that thermal stress in the fundational slab varies with differcnt para-meters. Nonuniform thermal stress of the slab lied on soft clay, especially on the silt of Shanghai, is emphasized. It is distinguished with hard rock base in which the influence of nonuniform thermal stress can be neglected when the ratio of slab thickness and length is rather small. |
