Based foundation for existing buildings and structures of reinforcement,the circular retaining structure system,adopts the elastic mechanics of cylinder pressure in the uniform method for actual engineering design.the effective use of construction space,reasonable force,effectively limit the deformation of foundation pit horizontal displacement of soil around etc,to fully consider the construction factors and economic factors of circular support provide a basis for the design and promotion.
