A method and system for quantifying crack morphology and predicting extension trend of tunnel lining

Abstract

The application discloses a tunnel lining crack morphology quantification and extension trend prediction method and system, and particularly relates to the technical field of network model analysis, and is used for solving the problem that cracks are regarded as independent individuals for analysis in the prior art and the overall evolution trend of a crack network cannot be predicted; a crack network with weights is constructed by identifying crack contours from time sequence images and establishing a network topological structure, analyzing the connection and spatial configuration among cracks, and further extracting topological role features and sub-network condensation features representing the network structure; a state transition network representing the macrostate evolution of a system is constructed based on historical data of these features; and finally, the possible state sequence in the future is deduced in the network with the current state as the starting point, so that the overall evolution trend of the crack network system can be predicted.
