Abstract
Large volume concrete structures are common structural forms in hydraulic engineering.Due to the fact that concrete structures are poor conductors of heat and have low tensile strength,large volume concrete is prone to significant temperature differences on the inner and outer surfaces,resulting in temperature stress and cracking.The temperature conduction equation of concrete structures is a partial differential equation,and conventional solving methods are cumbersome and have poor applicability.This article uses differential instead of differential to solve the temperature conduction equation,and provides a differential solution format for partial differential equations and boundary conditions.The results show that compared with conventional finite element methods,this method significantly improves the solving efficiency without reducing the solving accuracy.关键词
