In order to meet the requirements of the retaining and supporting structure for anti-slip performance, anti-overturning performance, bearing capacity and deformation, the material consumption, the size and the reinforcement proportioning of the retaining and supporting structure need to be increased, so that the economic value of the retaining and supporting structure is low.
