Abstract: The present invention has disclosed a movable water-permeable pile spur dike and an operation method thereof. The pile spur dike includes a fixed rail, a plurality of movable rails, a plurality of movable water-permeable piles, pressure sensors, flow meters and a control platform, wherein the plurality of movable water-permeable piles are arranged on the fixed rail and the plurality of movable rails, the pressure sensor and the flow meter are arranged at each monitoring point on the outer side wall of each movable water-permeable pile, the control platform is used for analysis and calculation according to the monitoring data from each pressure sensor and each flow meter and adjusts the positions of each movable rail and each movable water-permeable pile, so that the water flow velocity and spur dike's pressure at each monitoring point are less than a corresponding flow velocity threshold value and pressure threshold value.
