Composite pile wall support structure is a new type of composite support structure system composed of cement-soil pile wall and vertical pile through reinforced concrete roof plate. Based on a comprehensive summary of the types of composite pile wall support architecture and its calculation model, combined with field experimental research and numerical simulation, this paper proposes a design and calculation method based on the overall calculation mode of single-row small pile composite cement-soil pile wall support system, which provides a certain technical reference for the design and construction of the same type of foundation pit engineering.
