Abstract Research purposes: The summaries are made on the construction technology for embankment in permafrost zone of Qinghai-Tibet Railway based on analyzing and studying the working principle, construction methods, measure for ensuring construction quality and actual effect of construction technology of slice stone air-cooled embankment, thermal probe embankment, ventilation pipe embankment in permafrost area of Qinghai-Tibet Railway for the purpose of providing technical support to embankment construction in permafrost zone.
Research conclusions: The applicable scopes of different construction technologies in permafrost zone are defined after analysis in order to select rational construction technology. Thermal probe embankment with wide top is not suitable to adopt in the permafrost zone in which warm season is longer. Ventilation pipe embankment relates to wind direction , but now it is difficult for us to define wind direction, so it suggests to less adopt it as much as possible. The more attention should be paid to the quality of stone and prevention of surface water entering into slice stone air-cooled embankment and it is advised that bridge substitutes for deep embankment.
