More Information
Summary:The invention discloses a design method of a horizontal variable-rigidity foundation pit supporting structure. The design method comprises the following steps that three-dimensional modeling is conducted on the foundation pit supporting structure; lateral displacement of the supporting structure is analyzed, and a plane strain ratio is obtained through calculation; for an area with the plane strain ratio smaller than 1, the structural rigidity is redundant, the corner effect of a foundation pit is considered, the row piles are connected with the concrete supports, and rigidity adjustment is conducted according to an optimization expression of the plane strain ratio; for an area with the plane strain ratio equal to 1, two groups of row piles are arranged and are connected with the concrete support through the active rigidity adjusting device. The invention further discloses the horizontal variable-rigidity foundation pit supporting structure obtained through the design method. According to the method, the corn
