Sažetak
A paper proposes the framework, which would provide tunnel infrastructure managers with information on life cycle costs for remediation of structural cracks in secondary lining of tunnels. The framework is based on several characteristic phases, where the data between phases is transferred is automatic manner. The continuous, long-term, in-situ monitoring of behavior of tunnel and surrounding rock mass (phase 1) provides input data for the custommade neural network with back propagation algorithm, which is used to determine constitutive model input parameters necessary for numerical modeling (phase 2). In this way, secondary lining internal forces can be foreseen throughout the tunnel service life, with determination of cracking propagation rate in secondary lining (phase 3). Finally, life- cycle costs are determined using software for cost calculations (phase 4), adapted to the specific purpose, where the sole input of crack width gives an detail insight into life-cycle repair costs including man/hour, equipment/hour, material and other costs. The monitoring data will continuously be used to update and calibrate the crack repair costs, giving the tunnel managers real-time information and opportunity for proactive planning of tunnel maintenance, easing the overall decisionmaking process.
