摘　　要：根据我国寒冷地区地质、气象等方面的特点 ,对应用热管技术解决寒区地基冻胀问题的传热和冻结过程进行了数值分析 ,着重分析了不同气候条件、土壤性质及热管几何尺寸等因素对季节性冻土冻结过程的影响 。The technology of using heat pipe to prevent foundation from frost heaving showed very successful in cold region. The thermal and frozen processes of foundation with heat pipe were numerically analyzed in this paper. Main effect factors such as weather, soil characteristics and geometric size of heat pipe were investigated. The results will be very useful for practical application and design.
