环形超长混凝土结构温度问题研究

Study on the Temperature Problem of Overlong Annular Concrete Structures

利用有限元方法建立环形超长结构温度问题计算的有限元模型,对不同曲率半径的计算模型在季节温差下的温度效应进行计算,得出一些环形超长结构温度应力的分布规律,并得到了一些设计概念,可供环形超长结构设计中考虑温度作用时作参考。

A finite dement model is set up for calculating the temperature of overlong annular concrete structures. Through calculation on the temperature effect of the models of different radius of curvature, the characteristics and distribution of stress for overlong annular concrete structures are studied. Some design concepts which may be used as references for temperature effect analysis in the design of overlong annular concrete structures are proposed.
