摘要: 堆石混凝土作为一种新型材料已应用于水利、港口、采矿等诸多工程结构,目前,对于这种材料的应用仍处于发展阶段。为深入研究堆石混凝土的热力学特性,根据堆石混凝土结构的特性,建立等效的计算模型,确定堆石混凝土温度场的数理方程,并获得材料温度场分布的解析解。以一个堆石混凝土结构为例,借助Matlab的编程工具,分析了温度变化特性。计算实例表明,该解析法可用于研究堆石混凝土材料温度场的分布规律,为研究堆石混凝土材料的温度场变化奠定了理论基础。

Abstract: As a new-type material,RFC(rock-fill concrete) has been applied to structures of hydraulic engineering,harbor engineering and mining engineering. At present,the application of RFC is still in the stage of development. To research the thermodynamic properties,an equivalent model is built according to characters of RFC structure. The mathematical equation for the temperature field of RFC is constructed,and the analytical solution of temperature field distribution is obtained. Taking an RFC structure as an example,Matlab is used as a programming tool to analyze the temperature properties of the structure. Results show that the analytical method in this research could be used to study the temperature field distribution of RFC. It lays a theoretical foundation for the study of RFC temperature field.

Key words: rock-fill concrete, temperature field, mathematical equation, analytical solution
