摘要
分析总结现有地下工程围护结构传热研究不足的基础上,对实际贴壁式和离壁式衬砌地下工程围护结构进行合理的物理数学简化,建立了热传递过程的数学模型。该数学模型中详细考察了不同的边界条件。有限单元法对复杂区域具有良好的适应性,论述了有限单元法在地下工程维护结构传热中的应用。
This paper summarizes the existing deficiency of heat transfer of maintenance structure in an underground engineering,the actual paste wall and lining of underground retaining wall structure is simplified by reasonable physical and mathematical model,and the mathematical model of heat transfer processe is established.The mathematical model examines in detail the different boundary conditions.Finite element method has good adaptability to complex region,and this paper discusses the application of the finite element method for maintenance structure in the underground engineering.
