The Study Of Rural Roads Frozen Soil Treatment Program In Da Xinganling

Building roads in frozen soil regions, how to completely control the permafrost is currently still a worldwide problem, the world is actively looking for solutions, but there is still no cure for permafrost way, not much experience to draw on, and frozen soil around each have their own characteristics, for the overall experience of others can not be used. Especially rural roads that subject to the investment restrictions, in order to cure frozen soil occurrence of disease, is very difficult. As in the construction of roads during the frozen soil can not properly treated, after the completion of frozen soil disease will gradually occur, will affect the highway operational functions, will seriously affect driving safety.In order to solve the low investment in the construction of rural roads during the effective governance frozen soil, frozen to minimize the occurrence of disease, thesis Da Xinganling frozen soil situation and investment in rural roads, built on frozen sections of highway construction in rural areas the key technologies the research to identify the economic, rational and feasible solution, and has been promoted. Paper based on summarizing the past to build roads through permafrost disease cases, on the basis of collecting and analyzing relevant data of permafrost on the work have already done on the disease situation survey, disease analysis, research mainly generated Daxinganling region and major diseases permafrost Treatment program; through Treatment programs for different effects, cost analyzed in ensuring pavement design life cycle or are not affected under the overhaul period performance, considering rural road construction investment, research the best solution; through specific projects for implementation and observation, and ultimately determine the feasibility plan to determine the best solution to rural roads that are suitable for Daxinganling Treatment of permafrost regions.
