Abstract

The article describes a method for calculating the safety of extended structures, in particular tunnels. The probabilistic approach to solving the problem is analyzed using the reliability of the structure with the probability of failure-free operation and assessment of the residual life of the structure. These characteristics make it possible to predict the residual life of the structure within a time value until the design has exhausted its ultimate state. An assessment of the operational reliability of the structure is carried out by measuring and establishing existing structural defects. Based on the data obtained, an analysis was carried out and the residual life of the structure was calculated, as a result of which the method and timing of the elimination of faults is determined.
