Reliability Evaluation for Tunnel Lining with Cracks Based on Extension Theory

Abstract:

In order to solve the problem of multi-index amalgamation on the reliability evaluation for tunnel lining with cracks, this paper based on extension theory, use matter element model theory to establish the matter element of the reliability evaluation for tunnel lining with cracks, use the dependent function to establish the relevance between matter element and reliability grade, combine the research result of the Beiru tunnel lining cracks disease to evaluate the reliability. The results show that it could consider the multi-index of the cracks to use the extension theory to evaluate the reliability of the tunnel lining with cracks, and the evaluation results are more scientific and reasonable. It is viable to use the dimensionless parameters to represent the crack geometry. In the K6, the treatment scheme is mechanical reinforcement. In the K2 and K3,the treatment scheme is surface sealing. The reliability evaluation results supply theory basis and technical guidance for the tunnel long-term health service and the disease treatment.
