Abstract

Evaluation of integrated security situation for highway subgrade comprehensively and accurately has been able to provide the basis for repair of damaged subgrade in reconstruction stage after earthquake. Five indexes have been selected to figure characteristics of subgrade: damage condition, structural characteristics, such as height, slope ratio, etc., aftershock strength, features of terrain and physiognomy, rainfall intensity. Fuzzy AHP Comprehensive Evaluation Method, FACEM, has been introduced to determine weight of above-mentioned indexes and assess the general security degree of subgrade after earthquake. The research has shown that judgment results obtained by FACEM does almost match with advices given by professional experts after investigation. But there has been more persuasion and conviction with the quantitative approach to deal with uncertain information generated in process of evaluation for FACEM.
