摘　　要：通过对新旧规程中供热直埋热水管道摩擦力的计算分析,得出同条件下新规程单长摩擦力减小了很多,且考虑了地下水位对管道摩擦力的影响,指出摩擦力的变化直接影响到管道过渡段长度、自由端热伸长以及补偿器的选择等,其计算数据关系到管网的安全运行,具有重要的实用价值。Through analyzing friction computation of directly buried heat supply pipeline in old and new norms, the paper concludes that： single friction reduces by considering the impact of underground water level for pipeline friction, friction alteration directly influences pipeline transition section length, free heat elongation and compensator selecting and so on, the computation data will be some relationship with pipeline safety oper- ation. Thus, it has important application value.
