摘要
本文根据基础底板大体积混凝土的特点,采用有限差分法求解砼的温度场,用有限单元法分析砼的温度徐变应力,同时编制了相应的计算程序,给出了工程计算实例。
Based on the characteristics of fundation mass concrete, using finitedifference method the numerical solution of tmperature field is gotten,using finite element method.the numerical solution of creep-tmperature stress is gotien in this paper.The FORTTRAN computer programs Afor the determination of non-stationary tmperature field and creep-tmperature stress in mass contrete structures have been made,the examples of programs application in engineering are given.
