In our country at mohe———The line of Daqing crude oil pipeline project go through the permafrost section, its stabily of permafrost not only decide the stabily and safe operation of crude oil pipeline ,but also decide the degree of the freezing injury. There-fore, studying the happening reason and mechanism of freezing injury by the change of permafrost, taking action some useful prevention and control measures, protecting the stabily of permafrost, are the keys to solve and decrease freezing injury by building crude oil pipeline in permafrost section.
