用基岩各向异性热学参数分析混凝土基础块的温度徐变应力

Analyzing Thermal Creep Stresses in Base Concrete Block Using Anisotropic Physical Parameters of Bed Rock

本文提出了传统计算温度徐应力方法的缺点在于采用地基热学参数各向同性的假定．并证明了用由现场测定的各向异性热学参数算出的应力场较传统方法算得者为优。

This paper points out thatthe shortcoming of traditional method of calculating concrete thermal creep stress is the assumption of isotropic bed rockthermal characteristcs and gives an advanced method as well as an example into evidence.
