Abstract：Research purposes: As the exceptional cold wave occurs frequently in north China recently to cause the forst crack and leakage of the fire pipe installed in the station platform of high—speed milway，the fire equipments dont work efficiently．It is found in the investigation that the fire pipe installed in the platform is used only for hydrant with its ends connected with the water pipe for passenger train to form a parallel water supply pipeline network．When there is no water supply to passenger train，the water pressure in fire pipe is basically in equilibrium and the velocity of the water flow in fire pipe is low with a little heat exchange．Aiming at this problem，the discussion is made on the frost protection measure to wet or dry fire pipe system installed in platform of high—-speed railway in north China to provide the reference to design of fire—fighting system installed the platform of high—speed railway．
Research conclusions:The fire pipe installed in platform of hiIgh—speed railway in north China should be layed below the frost line of soil if possible．Otherwise，the frost protection measure should be taken to the wet or dry fire pipe system according the concrete local conditions．
