Study On Safety Evaluation System And Evaluation Method Of Highway Tunnel Structure

Because the tunnel structure safety is influenced many factors, the people painstakingly has not been synthesized ,since long ago to the tunnel structure safety to each factor the mensurable evaluation method. Based on this, this article according to the tunnel structure thecharacteristic, did to the highway tunnel structure safety appraisalinitially searched.First understood the safety system and the safe evaluation systemcharacteristic, the reference general appraisal system establishment principle, uses determines the nature of the principle selection whichunifies with the quota to the tunnel structure safe appraisal influence essential appraisal target; Finally, to appraises the targetto make quantification processing, and determines each appraisaltarget with the level analytic method the weight. From this, establishes the tunnel structure safe appraisal target system.Had determined after the safe appraisal needs the quanti—ficationtarget, selects the fuzzy mathematics method, establishes the tunnelstructure safe appraisal two levels of fuzzy syntheses appraisals model, carries on the synthesis appraisal to the tunnel structure security. Finally through the purple level ground shop tunnel example analysis, proved establishes the appraisal system and the method research has a stronger practical value.Through to the lining of tunnel structure value simulation analysis, verifies establishes the appraisal system and the method accuracy.
