Study On System Of Highway Tunnel Maintenance And Evaluation Technology

With a large number of highway tunnel of China entering the operational phase, tunnel maintenance work is more and more important, but maintenance and management of highway tunnel started late in our country, and it is still in the primitive stage of low efficiency. So does the highway tunnel construction structural evaluation, in the qualitative stage. In view of this, the related problems were studied in this thesis.Firstly, the disease formation mechanism of highway tunnel construction structural were analyzed, providing a basis for the disease treatment, and then the major remediation technology and application conditions on tunnel diseases has been systematically given according to the norms and the mature existing methods. Secondly, based on the analysis of the existing tunnel disease classification method, the fourth method used by highway tunnel disease levels, and the standard stipulation of the daily maintenance, regular, special and special test results, four determine grade level of highway tunnel maintenance technology, established a quantitative and objective-based evaluation system for highway tunnel disease, supplemented by qualitative and subjective. Thirdly, based on extenics theory and tunnel disease evaluation, by scaling to determine the weight of index level and the AHP method to determine the weights of criterion level, developed the evaluate physical element, festival field, classical field, a road tunnel safety evaluation extenics model established, so to realize the tunnel safety quantitative evaluation.This paper established a highway tunnel maintenance management database by the disease classification evaluation system and the standardized custody on the information of highway tunnel. Meanwhile, developed by SQLServer2005 and ASP.NET tunnel maintenance management system, through data entry, editing, query, and developing of other basic functions, the computer management of highway tunnel basic information, daily inspection of civil structure information, disease survey information and inspection information are fully realized, which is a technical support for maintenance and management of tunnel.
