Slope pile model test device under action of vertical and horizontal combined loads
A slope pile model test device under the action of vertical and horizontal combined loads comprises a horizontal loading device, a vertical loading device, a hoop, a universal bearing connector and ahoop, wherein the horizontal loading device is connected with a pile through a pulley and a steel cable, the vertical loading device is located at the top of the pile and connected with the pile through square steel and the steel cable, the hoop is used for connecting the pile with the steel cable, and the universal bearing connector is used for connecting the pile with the square steel; when thesteel cable is connected with the hoop, a horizontal load can be applied to the model pile; when the square steel is connected with the universal bearing connector, a vertical load can be applied to the model pile; And meanwhile, during connection, horizontal and vertical combined loads can be applied to the model pile. Compared with an existing loading device, the slope pile model test device under the action of the vertical and horizontal combined loads has the advantages that the device is suitable for experimental study of pile foundations with various sizes on various types of soil bodies, the friction influence generated by the device on horizontal movement of the pile top in the horizontal load applying process can be effectively eliminated, horizontal loads with different heights can be applied, it is guaranteed that the vertical load does not generate eccentric force on the pile body under the action of the horizontal load, and the bearing performance of the pile foundation under the action of the combined loads can be analyzed more accurately.
