Research on the stability evaluation method of anchored slopes based on group decision making and matter element analysis

Abstract This research is focused on the evaluation method of anchored slope stability, and an accurate evaluation method with a simple operation is proposed. Group decision theory and the analytic hierarchy process are used to determine the weight of each evaluation element, the correlation degree...
