The invention discloses a high buttress counter pull type inclined supporting structure used for foundation pit supporting, and relates to the technical field of rock engineering. The structure comprises a building envelope used for supporting the edge of the foundation pit and a buttress pile column which is arranged in the foundation pit and used for supporting the building envelope; a crown beam is arranged on the top of the building envelope, a circuit purlin is arranged on the side wall of the side, close to the foundation pit, of the building envelope, a strip support is arranged on thetop of the buttress pile column, the circuit purlin is connected with the strip support through a supporting arm, two rows of pile foundation columns are arranged between the building envelope and thebuttress pile column and are parallel to the building envelope, the height of the tops of the pile foundation columns is smaller than the height of the top of the strip support, and a sidespan bottomplate is arranged on the tops of the two rows of pile foundation columns for connection; the top of the sidespan bottom plate is connected with the strip support through an inclined pull arm column.The structure can effectively reduce the main construction difficulty, construction efficiency is improved, foundation pit earth and stone digging is facilitated, and the construction cost can be effectively reduced.
