%X Anti-slide pile is a major engineering measure to reinforce debris landslide. The interaction between anti-slide pile and sliding mass determines the reinforcement effect. Debris landslide is mostly composed of soil-rock mixture. A model for evaluating the macro-shear strength index of soil-rock mixture is introduced to calculate the sliding resistance of anti-slide pile in soil-rock mixture. A method of calculating sliding resistance in consideration of volumetric block proportion (VBP) and angle of repose (<i>δ</i>) is presented based on the theory of soil arch between piles. The design procedures of anti-sliding pile in soil-rock mixture are also proposed. According to the study of soil-rock mixture with a VBP of 20%~45% and <i>δ </i>of 25°~40°, the sliding resistance provided by anti-slide pile in soil-rock mixture is not always greater than that in soil. The safety of anti-slide pile depends on the value of VBP and <i>δ</i>, with a clear dividing line. Comparison with numerical simulation results verifies the rationality of the present method.
