Application Status and Prospect of Slope Treatment of Foundation Pit with Special Soils

With the development of society, there are more and more special soil slope projects in the construction of building foundation pits and roads. Because of the characteristics of difficult treatment of special soil, the research on slope treatment of special soil foundation pits has become the focus of current scholars. In order to ensure the safety and long-term benefits of foundation pit projects built in special soil, in recent years, many scholars have carried out in-depth research on slope treatment of foundation pit with special soil. Based on the detailed investigation of engineering examples, this paper summarizes the characteristics and treatment measures of soft soil, collapsible loess and expansive soil slopes in special soil, and provides reference and technical guidance for the research and development of foundation pit slope treatment in special soil.
