[0002] Retaining walls are engineering structures whose main function is to support roadbed fill or hillside soil to prevent these soils from deforming and becoming unstable. They can effectively support the stability of embankments or cutting slopes, as well as tunnel entrances and other locations. With the continuous development of urban transportation and the increasing shortage of urban land, conventional retaining walls are required to meet the functional requirements of municipal engineering while ensuring certain support conditions. Commonly used conventional retaining walls such as gravity retaining walls, cantilever retaining walls, and buttress retaining walls have simple structures and a wide range of applications. Their main function is to prevent soil from sliding and support the roadbed. However, this type of retaining wall has a single function and occupies a large area of foundation. Its use in some projects is very limited and cannot meet the actual needs of projects with limited land. Utility Model Content
