Zusammenfassung:The invention discloses a debris flow apron toughness protection structure design method which comprises the following steps: constructing an impact dynamics three-dimensional model of a debris flow apron at a toughness protection structure arrangement position, and simulating the impact dynamics three-dimensional model to obtain an energy threshold value E0 of failure damage of block stones to the apron; according to the energy threshold value E0, the dam height and the debris flow speed, the distance a between the tough bodies poured in the apron is calculated; at least half of the tough bodies in the apron are poured into concrete, and the distance between every two adjacent rows of tough bodies is made to be equal to the distance a between the tough bodies; and adjusting the tough bodies, arranging two adjacent rows of tough bodies in a staggered manner, and then throwing and filling rock blocks between the tough bodies to complete the design of the tough protection structure. 本发明公开了一种泥石流护坦韧性防护结构设计方法,其包括构
