Research On The Evaluation Model Of Serving Tunnel Health Inspection

There have most tunnels and rapidly developing in China, however, the health oftunnels is more serious for geological environment, large-scale and rapid development,moreover, the maintenance technology of tunnels starts later, and existing diagnosismethods of tunnels health is qualitative. This paper focuses on selecting the factors orindicators of serving tunnels health, division the levels of the health status,comprehensive evaluation criteria of the indicators, comprehensive evaluation model fortunnel health, etc, mainly results:①Tunnel health status is divided into four levels in the paper, which is base onthe tunnels Health existing classification and the special inspection levels of “Technicalspecifications of the highway tunnel maintenance” in China, and then, the servingtunnel health levels have established.②According to selection principles of integrated evaluation index, integratedevaluation indexes of serving tunnel health have selected, which is base on analyzingstructure damage morphology, six A-indicators have been identified in the paper,namely: Lining cracks, Leakage, Lining material deterioration, Hole behind of the lining,Clearance of lining deformation, Lining up or spalling，and15II-indicators, and then,integrated evaluation index system has established for serving tunnel health with thetheory of AHP.③Analysis of the existing criterion of serving tunnel health status indicators, andthis method is given criteria on the basis of those;④It’s important problem to analysis of solution for the evaluation matrixes in theGRA-Fuzzy integrated evaluation model, grey correlation coefficient alternative fuzzymembership of feasibility, a simplified AHP model to solve the weight of the indicators,selection of Fuzzy operator, processing the results vectors, and so on. Then, basis ofthose solutions, the evaluation model has established with grey correlation degree andfuzzy integrated evaluation theory, at the same time, the model has been described andverification with engineering and the result shows that the model is reliable.
