Application of Improved SPA Method in Earth-Rock Dam Safety Assessment
摘要
Abstract
This study proposed an improved set pair analysis (SPA)method by using malleability of original relation degree to solve the problem of subtle differentiation between uniform,different and reverse in standard SPA. The improved method further subdivided difference and reverse into excellent difference,inferior difference,excellent reverse and inferior reverse. At the same time,considering the uncertainty of the important degree of the evaluation index,the reliability of the expert scoring and the dynamic difference between the experts,the method determined the index weight based on the uncertain type of AHP method. An earth-rock dam safety assessment model was developed with this model for the evaluation of the excellent inferior tendency degree of the earth-rock dam in the security level rank. Example analysis shows that,comparing with the standard SPA method,the improved method is more refined and close to the reality and the improved method is reasonable and feasible.关键词
