Study On Comprehensive Benefits And Countermeasure System Of Inclined Shaft Installation In Highway Tunnel

In recent years,it has become a common practice to use inclined shaft as construction auxiliary tunnel and ventilation shaft in highway tunnel.However,the comprehensive benefits of the inclined shaft has great influence on the whole benefit of tunnel construction and operation.In this article,the comprehensive benefit evaluation of the inclined shaft setting of the highway tunnel is taken as the general objective,in the process of evaluation.Firstly,all factors affecting the installation of inclined shaft are comprehensively analyzed,and the control factors of design and construction of inclined shaft are given.Secondly,according to the mutual affiliation between factors and the relative importance of the comparison factors,according to the idea of Analytic Hierarchy Process,combining the principles of establishing indicators,the four level index system has been established.That is,a goal,three criteria,four sub criteria,and 38 indexes.Thirdly,according to the principle of Analytic Hierarchy Process(AHP),The scale of mutual importance between two elements is scaled by 1-9 scale method,a judgement matrix with positive reciprocal invertibility is established,Using the method of sum product to calculate the comprehensive weight of each index for the total target,Then according to the characteristics of the indicators,the relevant specifications,statistical results and engineering experience,The combination of qualitative and quantitative methods is adopted,the 38 indicators were divided into scoring standards.Finally,in this article,a Java and Java Script technology are used to develop a Web based on " Comprehensive Benefits and Countermeasure System of Inclined Shaft Installation in Highway Tunnel ",and the feasibility of the countermeasure system is verified by an example of inclined shaft installed in a tunnel.
