Anti-slide piles can be a single pile, a double pile, or a combination of multiple piles, and are sometimes used in conjunction with other retaining structures (such as retaining walls, anchors, etc.). When designing, factors such as geological conditions, soil type, slope, and loads (such as additional loads caused by earthquakes, rainfall, etc.) need to be considered.

The above method is based on the strength reduction method, by reducing the strength parameters of the channel slope body and the soft interlayer, introducing the concrete replacement ratio and the anti-slide pile bearing coefficient, combining the two to form a variety of working conditions and calculating the corresponding safety factor, comprehensively determining the combination of concrete replacement amount and anti-slide pile parameters from the perspective of construction difficulty and economy, and completing the reinforcement construction of the channel slope.
