Application of analytic hierarchy process in optimization of deep foundation pit support scheme
YANG Ao-bao;CHEN Rui-min;School of Civil Engineering,Henan Polytechnic University;
The choice of supporting schemes for deep foundation pit is mainly considered from four aspects: safety and feasibility,convenient construction,economic rationality and environmental protection. The AHP is adopted to evaluate the foundation pit support scheme,and the complex problem is simplified by establishing an evaluation hierarchy model. The maximum characteristic root method is used to solve the weight value of each factor of the judgement matrix. Finally,a quantitative comprehensive evaluation result is obtained by the fuzzy comprehensive evaluation method. This result provides the basis for the selection of the deep foundation pit support scheme. The feasibility and practicability of the method are verified by engineering examples.
