分析了混凝土温度裂缝产生机理，应用混凝土的温度收缩裂缝控制理论对2．4m厚的地下室底板进行计算分析，为地下室底板的施工提提供了理论依据。%The mechanism of temperature cracking of concrete is analyzed based on the temperature cracking of 2.4m thick concrete of the base plate of basement and the theory about crack-control in concrete structure by drying shrinkage and temperature difference of atmosphere. It is the theoretical basis of the construction for base plate of basement.
