中文摘要：

针对U型地埋管换热器的特点，在分析单井换热器换热量的基础上，考虑到多井换热器井与井之间传热的相互干扰，提出了一种用于U型地埋管井群换热器数值计算的9井模型，这种模型在数值计算时既能代表一般井群换热的规律，又便于计算机处理，为实际工程中分析井群换热规律提供了很好的理论依据。

英文摘要：

Aiming at the features of vertical u-tube ground heat exchangers, based on the heat analysis of single well heat exchangers, and the mutual interference between heat exchanger wells on heat transfer was considered, a u-shaped ground heat exchanger tube numerical calculation of the nine wells model was proposed, the model in the numerical calculation can represent the heat ex- change principle of general well, and convenient to computer processing, which provided a good theory for the analysis of Well heat transfer rules in practical engineering.
