建立了大体积混凝土温度场的数学模型，在一维散热情况下．用差分方法给出了数值解．在天津奥林匹克工地进行了现场测试，分析了理论与实际测试的区别，并提出了在施工中控制裂缝所采取的措施． A mathematics model of the temperature field of mass concrete was established, in the case of one-dimensional heat dissipation. The numerical solution is given using the difference method. Field tests were conducted at the Tianjin Olympic site to analyze the differences between the theoretical and practical tests, and proposed measures to control cracks during construction.
