The temperature control of massive concrete pile cap

摘要

The temperature control nature of the massive concrete is to control the temperature stress caused by temperature difference. Taking the pile cap of China Expo Exhibition Center as an example, this paper calculated the internal and external temperature of massive concrete and discussed the specific measures of temperature controlling, according to the plane strain theory established a numerical model, simulated and analyzed the temperature and stress field in pile cap. The results provide a theoretical support for the pile cap construction.
