  • In seasonal frozen zones, protection technology for heaving damage and slope stability of expansive soil slopes is necessary. By analyzing the engineering background and characteristics of expansive soil, that it is considered protection goal of expansive soil slopes is to try to suppress the amplitude of the water content of the destruction zone so as to ensure that the soil structure of slope is not destroyed and crack development is restricted. Based on the theoretical researches on frost heaving and swelling characteristics of expansive soil, the comprehensive protection technology with both waterproofing and drainage is proposed to ensure the long-term effectiveness of protective measures.
