结合工程实例，在对长期运行、有热堆积问题的埋地管群换热器进行数值分析的过程中，提出处理埋地管群壁面边界条件的新方法———均摊恒定热流法，并用此方法分析了热堆积问题下土壤温度场的变化，验证这种方法的合理性。分析了热堆积问题对埋地管群换热器运行带来的恶劣影响，并用均摊恒定热流法分析增设室外冷却塔的可行性。
結閤工程實例，在對長期運行、有熱堆積問題的埋地管群換熱器進行數值分析的過程中，提齣處理埋地管群壁麵邊界條件的新方法———均攤恆定熱流法，併用此方法分析瞭熱堆積問題下土壤溫度場的變化，驗證這種方法的閤理性。分析瞭熱堆積問題對埋地管群換熱器運行帶來的噁劣影響，併用均攤恆定熱流法分析增設室外冷卻塔的可行性。

A new method to process the buried pipelines boundary conditions - average constant heat flux method is proposed, combined with engineering case, during the period of studying the buried pipelines heat exchanger in the long run and with the heat accumulation. The method is appropriate to ana-lyze the changes of soil temperature field under the condition of heat accumulation; the rationality of the method is illustrated. Finally, it analyzes the shortcoming caused by heat accumulation of buried pipelines. The feasibility of installing outdoor cold tower is verified through the average constant heat flux method.
