The local factors such as topography, vegetations and soil moisture contents, have great influences on the distribution, ground temperatures, and ground ice contents of permafrost. About 50 km of wetlands have been identified along the China-Russia crude oil pipeline route. In these segments, the surficial deposits consist of peat and humic layers on the top of thick ground-ice, or ice-rich permafrost. The frozen ground engineering geology conditions in wetlands generally are the worst for building and operating the pipeline. The hazardous periglacial processes, such as the widespreadpresence of pingos, icings and frost mounds due to the extensive occurrence of the frost-susceptible soils and ample supplies of surface and ground waters in winter pose significant threats on pipeline operation.
