大体积混凝土水化热温度场三维有限元分析

利用结构有限元分析程序Super SAP对大体积混凝土温度场进行模拟计算，对计算结果进行了分析，寻找大体积混凝土温度场分布存在的规律，为Super SAP在大体积混凝土温度场预测中的应用提供理论分析的依据。理论分析表明，表面边界条件不同，温度场的分布存在规律性的变化，边界条件相同时，温度分布存在对称性，反之不存在对称性，并且基础沿厚度方向的中心截面具有对称性。

Analysis of massive concrete 3-dimensional finite element hydrated heat temperature field

The massive concrete temperature field is analysed by Super SAP structure finite element method a-nalysis program, together with the disciplinary of distributing of massive concrete temperature field to provide the theoretical basis for the use of forecast of massive concrete temperature field. The academic analytical result indicates that the center temperature of the mass concrete is topmost, then gradually recedes from center to surface, and temperature gradient reduces from surface to center. Because of the difference of the boundary condition, the temperature field distribution is symmetrical, but when boundary condition is distinet, the temperature distributing is unsymmetrical.
