| With the rapid development of transportation and promotion of national economic,freeway construction brings a negative influence on ecological environment, such asexcavation and filling works which destroy the original topography and vegetation, exhaustemission and wastewaters produced by construction. The main works of environmentalprotection are different because the highway corridors pass through different territorialenvironment. Due to the special climate, hydrology, geology and other factors in cold regions,eco-friendly technologies for environment needs to be explored in order to protect theecological environment along the corridor.Analyzing domestic and abroad research results, combined with the actual constructionof projects, using the method of field survey research and test analysis, the key technologiesof environmental protection in cold regions are studied. Analyzing the ecologicalcharacteristics in cold region, discussing the influences of highway construction onenvironment and the main difficulties of environmental protection, the key technologies ofenvironmental protection in cold region have been proposed. Relying on the project, thevegetation bags gridding technology for rock slope in cold region is demonstrated andproposed. Through investigation, selection and introduction of vegetation, the suitablevegetation species and configuration mode are proposed, and ecological environment ofrock slope are also restored. Against the actual construction of service area, the paper presentscomposite ecological soil treatment technology for wastewater, ground source heat pumpsystem and solar power electricity system, which use resource efficiently and build anecological and energy savingservice area.The researches enrich construction experience of ecological and environmentalprotection for freeway in cold region, which resolve the key technologies issues ofeco-friendly highway in cold region, and also promote the continuous development oftransportation in cold region. |
