摘要
研究气温骤降引起大体积混凝土温度变化和温度应力的计算方法,给出气温骤降引起的温度变化规律及温度应力情况,进一步论证了采取适当的保温措施是抵御寒潮的有效途径这一结论,并得出温度和温度应力计算的简化公式.
A study was performed on the method for calculation of cold waveinduced temperature variation and temperature stresses of mass concrete, and the regularity of temperature variation and distribution of temperature stresses were given. It was verified that the adoption of a certain measure for temperature preservation was an effective way to resist cold waves. Besides, A simplified formula for determination of the temperature and temperature stress was given.
