ABSTRACT:

    To establish a more realistic and comprehensive algorithm to assist decision makers in optimizing a route in a permafrost regions, the optimal design should be determined and funds should be used more efficiently. In this paper, we used the permafrost subgrade treatment, the permafrost distribution, geological engineering conditions,interference of facilities along the route, route length and 10 other indicators to reflect the factors affecting the selection of route in permafrost regions. An optimization model for highway route scheme was established based on matter element theory by comparing the optimal value of each evaluation program. The weight of each index was determined by an analytical hierarchy process. A case study shows that the optimal model was simple and intuitive, providing a new comprehensive evaluation method for route scheme selection considering the unique geological conditions in permafrost regions.

    Cold Regions Science and Technology is an international journal dealing with the science and technical problems of cold environments in both the polar regions and more temperate locations. It includes fundamental aspects of cryospheric sciences which have applications for cold regions problems as well as engineering topics which relate to the cryosphere.

    Emphasis is given to applied science with broad coverage of the physical and mechanical aspects of ice (including glaciers and sea ice), snow and snow avalanches, ice-water systems, ice-bonded soils and permafrost.

    Relevant aspects of Earth science, materials science, offshore and river ice engineering are also of primary interest. These include icing of ships and structures as well as trafficability in cold environments. Technological advances for cold regions in research, development, and engineering practice are relevant to the journal. Theoretical papers must include a detailed discussion of the potential application of the theory to address cold regions problems. The journal serves a wide range of specialists, providing a medium for interdisciplinary communication and a convenient source of reference.
