摘要：

In order to evaluate the health condition of the tunnel, the multi-level extension assessment model and calculation process of tunnel structure health were constructed. Taking distress detection of a tunnel section as an example, the classification criteria and evaluation index system were given. The structural health grade of the section was evaluated after normalizing the relevant detection values of the evaluation indices. The results show that the health level of tunnel structure in this section that belongs to sub-health and need to be repaired. The distress grade of each criterion layer was obtained. The influence of lining deformation and cavity on the health of the tunnel is the level of damage and the influence of seepage water, and cracking is the sub health level. Therefore, it can take different reinforcement strategies, for instance, grouting or drainage for seepage; repairing or grouting with bolts for cracks, grouting or backfilling for void, etc. © 2020, Central South University Press.
