【Abstract】 A study was performed on the method for calculation of cold waveinduced 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.更多还原
