【Abstract】 The cracking of sluice piers under construction is a troublesome problem.If we want to know the effect of temperature on the piers,it’s necessary to develop a numerical method to simulate the properties of concrete,the construction progress,and the variation of the environment.In this paper the authors analyzed the temperature field and stress of the piers by use of FEM computer program based on the computation theory and code design method for numerical simulation.Adopting some measures from the material property,control of temperature,construction and mainetenance methods,temperature difference between interior and exterior faces was reduced.Craking on the concrete faces resulting from quick change of temperature was prevented.This research work has great significance in practical engineering.更多还原
