As the number of operational tunnels is increasing incredibly fast, the maintenance pressure to ensure the structural safety of the tunnels thus becomes more and more intensive. This paper presents an integrated resiliency assessment model for tunnel deformational performance with the full utilization of field data from non-intrusive inspection and real-time monitoring system. A moving tunnel inspection vehicle (named as MTI-100) is developed for the inspection of the whole tunnel inner surface with a moving speed at 5km per hour for a minimum size of crack width at 0.3mm. Then the concerned key section of tunnels could be focused and the wireless sensing network (WSN) system is installed on the key section for real-time detailed monitoring of structural behaviors, i.e., deformation in this paper. After obtaining the huge amount of inspected and monitored data, a field-data-based resiliency model is built to analyze the resiliency behavior of tunnel structural performance. By doing so, the rational recovery strategy in terms of optimized recovery timing and recovery measures could be derived with the proposed resiliency model. Hence, an integrated assessment system for preventive maintenance, consisting of non-intrusive inspection at first, real-time monitoring at the second, and rational resiliency assessment with recovery implementation at the last, is established and well-validated by a real case for a shield tunnel in Shanghai metro line 2 at the end of this paper.
