| Abstract: | Water is one of the important factors that affect permafrost subgrade stability. Through investigation and test, the major subgrade diseases in permafrost area of Qinghai-Tibet Highway and site the distribution of subgrade moisture in typical section are analyzed. Under this basis, the influence of moisture on subgrade diseases is also analyzed. The results proved that water and thus increase of water content in soil mass would accelerate stability. is the key subgrade factor for s deformation to further affect its |
