摘要
本文通过大体积混凝土基础施工的温度监测和热工分析对比,总结不同厚度混凝土内部和外表温度发展的规律;核算基础混凝土各龄期阶段的温度应力值。同时对混凝土水化热绝热温度的计算公式,提出探讨意见。
Comparing temperature testing with thermo-technical analysis in construction of mass concrete foundations,We can sum up the temperature development of all size of the concrete blocks both inside and outside,and check up the temperature stress in each age of concrete.A comment on formula of the thermo-insulated temperature of concrete hydration is also made.
