摘　　要：地面发生火灾时会对土壤、地下管道及输送的油品温度产生影响,将原有的热平衡破坏而出现新的温度场;即使在火灾被扑灭后的一段时间内,土壤、管道温度会继续升高,仍有可能造成管道失效。针对此情况建立了非稳态传热模型,进行了数值模拟并对结果进行了分析,为后续管内输送介质温度分布的研究提供了科学的依据。When fire happens on ground surface, the thermal balance is destroyed, soil, buried pipeline and soil＇s temperature will increase. Even when fire has been put out, the pipeline would be failure for the increasing of soil and pipeline＇s continuous temperature. The unstable heat transfer model is developed for this instance, numerical simulation is made and the result is analyzed. The establishment of this model has laid the scientific base for further study on effect of a ground surface fire on medium transported in buried pipeline.
