Summary:The embodiment of the invention relates to a design method of a supporting structure of a deep foundation pit of a wading bearing platform and the supporting structure. Comprising the steps that a steel sheet pile is inserted into a first preset depth below a soil layer, the soil layer sequentially comprises a gravel pebble layer and a marble rock layer from top to bottom, the gravel pebble layer is located within the first preset depth below the soil layer, and the marble rock layer is located in the area below the first preset depth of the soil layer; and when the foundation pit is excavated at the position away from the bearing platform by the preset distance, a reserved soil step is designed at the edge of the inner side of the foundation pit, the shape of the reserved soil step is a right trapezoid, the right-angle face of the reserved soil step abuts against the steel sheet pile, and the reserved soil step has the preset top width, the second preset depth, the to-be-determined bottom width and the prese
