摘要： The present invention belongs to the field of slope stability evaluation and disaster prevention technologies, and relates to an evaluation method for a slope sliding area. An initial sliding surface corresponding to a minimum safety factor of a slope, a 5 corresponding initial sliding area and an initial weight are first calculated; then a possible sliding region of the slope is covered, a plurality of feasible sliding surfaces are randomly generated to simulate the possible sliding region of the slope, and secondary safety factors of the feasible sliding surfaces are calculated; and feasible sliding surfaces with secondary safety factors less than or equal to 1 are taken as secondary invalid sliding 10 surfaces, then areas of the secondary invalid sliding surfaces are calculated one by one, all the secondary invalid sliding areas and the initial sliding area are accumulated without repetition, and finally the slope sliding area is evaluated by using a cumulative value. An error value of the slope sliding area calculated according to the present invention is relatively small, and the slope sliding area may be used for preliminary evaluation of the 15 consequences of slope sliding.

摘要： A landslide failure morphology-based method for comprehensively evaluating the side slope risk, which relates to the fields of side slope stability and risk evaluation.
