| Abstract: | Using the principle of superposition, a simplified computational method of mass concrete surface temperature change, the lowest temperature value and temperature stress is provided when the temperature drops quickly. Temperature change laws of mass concrete surface owing to the temperature drop, under the condition of different concrete age times and the different surface protection measures are presented. Combining practice project, the surface protection measures which should be taken during the temperature drop are researched. |
