Analysis on fuzzy decision-making of foundation pit support system based on improved Analytic Hierarchy Process

Based on the systemic analysis on the related indexes of the evaluation of retaining and protecting structure for foundation pit, a relatively integrated evaluation index system of foundation pit support system was established. By making use of the method of improved Analytic Hierarchy Process which could satisfy consistent verification naturally, the synthesized weight of every evaluating factors were calculated, furthermore, the fuzzy mathematics method was combined with to calculate the superior and inferior level of each put forwarded scheme for foundation pit support, that means all of the schemes were evaluated quantitatively, and finally, the optimum scheme among of them could be obtained.
