Research on evaluation of highway tunnel lining cracks based on membership function
The distribution and spreading of tunnel lining cracks are direct reflection of the health condition of lining structure.In this paper,the crack width,length,depth to thickness ratio and angle are used to construct the evaluation indexes.A corresponding membership vector function B is established based on ridge distribution,and the weight vector R of each factor is determined through fuzzy matrix analysis.S=R·B is defined as the crack safety level vector,and the highest level is taken as the crack safety level.Based on this evaluation method,the cracks of a tunnel are evaluated.
