基于非均匀散热边界的大体积混凝土温度应力场分析
Surface Thermal Insulation of Mass Concrete During Cold Wave
摘要
Abstract
The surface thermal coefficient of mass concrete has a close relationship with boundary wind speed;a simple uniform thermal boundary assumption can not meet the need of temperature control calculation of complex boundary in the actual project. So the nonuniform thermal coefficient boundary method based on wind speed is proposed. And the mass concrete three-dimensional finite element model is established; and the temperature field and stress field are calculated. Compared with the uniform coefficient of thermal boundary conditions, the influences of nonuniform thermal boundary on temperature control of mass concrete are analyzed.关键词
