Abstract：The thermal probes，as a kind of effective method to protect permafrost actively，are used widely in Qinghai-Tibet railway and some other places with permafrost distributed. Some basic situations are presented about the thermal probes used in Fenghuoshan test subgrade of Qinghai-Tibet plateau，and analysis is made on its operation state and the change of ground temperature field around it. Finally，it is concluded that the thermal probes are effective to decrease the base temperature and to protect permafrost，and thus it can be used in permafrost regions.
