摘　　要：文章通过对大气-热管-土体耦合传热模型进行分析简化,采用ANSYS有限元分析系统建立了热管路基三维传热模型,并以青藏铁路北麓河地区气候条件和地质条件为背景,对普通路基和热管路基进行了模拟计算与对比分析,得到了两种冻土路基不同时刻的路基温度场变化规律。Based on the simplified air-heat pipe-soil heat transfer model,heat pipe subgrade 3D heat transfer model is established by ANSYS FEM system.With the background of climate and geological geology conditions in Beiluhe Region of Qinghai-Tibet Railway,simulation and comparison of normal subgrade and heat pipe subgrade were completed,and temperature field variations of normal subgrade and heat pipe subgrade at various time were collected.
