摘要
隧道衬砌裂缝的分布及扩展状态是衬砌结构健康状况的直观体现.本文以裂缝宽度、长度、深厚比、角度构建评价指标,基于岭型分布建立了对应的隶属度向量函数B,通过模糊矩阵分析法确定裂缝评价指标各因素权重向量R,定义S=R·B为裂缝安全等级向量,以最高一级作为裂缝的安全等级,并按本评价方法,对某隧道的裂缝进行了评定.
Abstract
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.
