Abstract：Research purposes: The treatment principle and preventive measures were put out for the major types of water disaster in permafrost area on Qinghai-Tibet Railway in combination with an example of engineering design and construction site situation of the second phase project of Qinghai-Tibet Railway.
Research methods: First the description was given theoretically about frozen soil and permafrost, and then the result was presented based on the analysis of various types of water disasters occurred in subgrade construction, culvert construction and bridge construction for the second phase project of Qinghai-Tibet Railway.
Research results: Although various types of water disasters occurred in constructions of subgrade, culvert and bridge were different, but all of them would influence the service of Qinghai-Tibet Railway in future in different extents, so the relevant measures should be taken.
Research conclusions: The principles of engineering design and construction of railway in permafrost area should suitable for various geologic characteristics of permafrost. The scientific analysis should be made and concrete treatment measures should be taken in order to guarantee economic rationality, safety and reliability of construction of Qinghai-Tibet Railway. Also the rational preventive measures should be taken for subgrade, culvert and bridge during the period of service in order to guarantee the quality and normal traffic of Qinghai-Tibet Railway, and fundamentally restrain the occurrence and development of water disasters, such as deformation and crack.
