Research on Treatment Scheme Optimization for Slope Based on Analytic Hierarchy Process

At present, there are numerous treatment schemes for slope, while there is a lack of research on scheme evaluation and optimization. According to analytic hierarchy process, this paper takes two treatment schemes for Cangshang pit slope as research object, which are reducing load by cutting slope and strengthening by grouting, handles the complicated problem hierarchically and systematically, and establishes hierarchical structure model. Judgment matrixes are constructed to analyze multiple factors synthetically, which combine qualitative analysis and quantitative analysis preferably, and optimal scheme is selected finally.
