摘要
本文对地基水平约束τ－ｕ 关系用折线模型替代了常用的直线假定，推导出有关计算公式。通过实例计算，表明本文方法比较符合实际情况，更具有一般性，适用于各种地基。
In this paper, with polygon line hypothesis of τ-u relationship of horizontal restrained condition of foundation instead of the linear model in common use, a new analytical method to calculate thermal stress of mass concrete structure on foundation is presented. By this method, the relevent theory and formulas is deduced. From the calculation of engineering examples, it is proven that this method shows more generality and can be applied to all kind of soils.
