Abstract

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. Furthermore, illustrative example has been given with damaged subgrade of national highway G212 after 5.12 Wenchuan 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.
