摘　　要：在埋地管道中,正温输送的埋地天然气管道会对山区土壤有一个放热影响,为解决山区土输气管道周围土壤的温度变化问题,以我国西部某管道为例子,基于该地区的土壤特性参数,采用FLUENT密集网格法对山区土的温度场特性进行模拟研究,对比了管道不同里程、不同季节、是否有保温层3个条件下的温度变化情况。结果表明:距离出站口越远的位置既里程越大温度越低,季节变化能够影响埋地管道土壤温度变化情况,埋地输气管道在有保温层的情况下与不设置保温层的输气管道相比发现保温层对管道热量起到一个防扩散作用。In buried pipelines,buried natural gas pipelines transported at positive temperature will have an exothermic effect on mountain soils,to solve the mountain soil temperature changes of the soil around pipeline,taking a pipeline in western China as an example,based on the region soil property parameters,FLUENT dense grid method was used to simulate the temperature field characteristics of mountain soil from three aspects:temperature change comparison of pipeline with different mileage,different seasons and with or without insulation layer.The results showed that the farther the distance from the outlet was,the lower the temperature was,the greater the distance was,the lower the temperature was,the seasonal change had effect on the soil temperature changes of the buried pipeline.Compared with the gas pipeline without the insulation layer,the insulation layer played an anti-diffusion effect on the heat of the buried gas pipeline.
