Research On Application Technology Of Highway Tunnel Health Diagnosis

Based on the studing of the status of highway tunnels,this paper studes the integral diagnosis way of health status for highway tunnels as folowings:1)Considering the characteristic of integral diagnosis of health status of highway tunnel, and according to the six principle of integral diagnosis of health status of highway tunnel,this paper generates the diagnosis targets for it,and builds the integral diagnosis target system of health stats for highway tunnel.2) On the basis of integral analysing the health degree of highway tunnel, this paper determines that the degree of health status of highway tunnel taes the four degree way,wath's more,this paper builds the degree of highway tunnel on the basis of four degree qualification of special examination results of highway tunnel.3)Through integral analysing the qualification standard alover the world,this paper builds the qualification standard for crack of lining,leak water,lining material deterioration, qualitativly and quantitativly,hiding cavity of liner,deformation,shifting and setting of liner, peeling and apalling of liner.4)On the base of studing the data weight factor of diagnosis of highway tunnel health status integral diagnosis index system,this paper builds scale weight factor of index for index-and criteria-layer using Analytical Hierarchy Process.5) Through studying the fuzzy integral evaluation theory,this paper builds the fuzzy integral evaluation model for highway tunnel health status. Whats more, this paper gives a quantitative diagnosis result of a working tunnel using the resuls.The paper achievements hasve certain guiding sense and application value for construction and the maintenance of highway tunnels.
