Degenerative Permafrost Engineering Geology Features Analysis and Forecasting of National Road 214
The paper is based on information of permafrost engineering geology of National Road 214, and for a comparative, analysis the permafrost engineering geology features of National Road 214, Including permafrost ground temperature, ice content, natural permafrost table and artificial permafrost table; Then Summary the distribution of permafrost of National Road 214, including Southern limit of permafrost and Northern limit of permafrost, Then get one conclusion; Because of the outside temperature increase and under the influence of the role of the project, frozen ground temperature has rise trends, The permafrost along the road all tended to degenerate, Then summary its degeneration features of National Road 214, and analyze the reasons of the final degeneration; Final, combining the high-speed reconnaissance and design project National Road 214, Analysis the permafrost existing meteorological data and geological survey data, according to the frozen ice content and permafrost thickness, Then to predict and analysis permafrost degeneration tendency in numerical simulation.
