| Abstract: | The permafrost conditions of Qinghai-Tibet Highway is going worse and worse after opening to traffic in the 1950s, especially after the construction of blacktop of the pavement in the 1970s to 1980s. On the basis of the environmental evolution rule along Qinghai-Tibet Highway, the analysis of the inner-relations of frozen soil conditions, ecological environment and foundation stabilization is carried out, the counter-measures for protection of frozen soil and ecological environment presented which is valuable for the design of environment protection and highway in permafrost region. |
