摘要
引入成熟度的概念对传统的早期混凝土温度应力有限元计算方法进行了改进。该方法考虑了温度和龄期对水泥放热速率和混凝土弹性模量发展的影响。通过对某大体积混凝土桩承台的现场测温以及温度应力的有限元实例分析 。
The conventional finite element analysis method of the thermal stress in mass concrete at early ages is improved.The maturity method of concrete is introduced with the consideration of the temperature effect on heat liberation and E-modulus development.The results of a temperature measurement test and finite element analysis of a pile cap is presented and discussed.
