Abstract: The main reason for the melting-settlement of highway bed in the permafrost area in Daxing'an Mountain is artificial swamp transformation whichdeteriorating the surface run-off condition and raising heat exchange betweenthe surface water and the permafrost. Method with best economic benefit ofblocking the base bottom of the culverts with sacked clay and applying themalinsulation technique with foamed plastics i. e is suggested to deal with the melting-settlement of highway bed. It is also pointed out that assessment ofenviroment effect of large scale planting or construction is necessary.
