As an important urban infrastructure, urban road tunnel is often half-concealed in water and soil strata and it is hard to be observed and detected. In this paper, a comprehensive evaluating system of tunnel structure is established regarding the specificity and importance of urban road tunnel structure. The technical condition of tunnel structure is evaluated by analytic hierarchy process (AHP) method. The hierarchical decomposition of road tunnel structure is proposed; the maintenance records and disease characteristic indexes are combined; the deducting scores of the same disease in different development degrees are given; the importance of members and sections of tunnel is considered and their weights are calculated, to complete the evaluation of technical performance of urban road tunnel structure through calculating the member disease evaluation index, structure section evaluation index and tunnel overall evaluation index. ©, 2015, Editorial Office of "Modern Tunnelling Technology".
