以强度为主设计直埋供热管道敷设长度的合理性

The Rationality Based on the Strength in Designing the Laying Length of Directhy Buried Heating Pipelines

本文论证了有补偿直埋供热管道以强度条件确定敷设长度的合理性，同时导出了相应的设计计算公式．指出依据强度条件确定管道长度后．轴向稳定条件能够自行满足，并用实例对以上理论分析进行了验证．

This paper demonstrates the rationality in designing the laying length of compensable directly buried heating pipelines and derives its relevant calculating formulas. The author points out that the axis stability can be automatically satisfied if the pipeline length is decided on its strength. Finally, the above theoretical analysis is verified with an instance.
