Based On IE Theory,the Research On The Anti-destruction Of Xi’an Urban Hub Site

With the rapid development of urban construction,the rapid improvement of economy,the continuous expansion of urban population,increasing travel pressure,the scale of urban subway is also expanding.Although urban subway can provide high-speed and convenient travel mode,due to the continuous increase of subway operation time and passenger flow,the operation risk of subway is also expanding,which makes more and more metro invulnerability failure and threatens the safe operation of subway.This paper studies the invulnerability of Xi’an hub station by IE theory.First of all,based on the definition of Metro invulnerability,according to the questionnaire survey of Xi’an hub station,this paper analyzes the current situation of Xi’an hub station with the help of SPSS software,and finds out the problems of Xi’an hub station.Secondly,through the analysis of the exogenous and endogenous factors of Xi’an hub site’s invulnerability,the interpretive structure model of the influencing factors of the hub site’s invulnerability is established to identify the hierarchical relationship of these influencing factors and finally determine the most critical factors.Thirdly,according to the influencing factors to build the invulnerability evaluation index system,through the combination of Delphi method and rough set theory,the weight of the invulnerability evaluation index is analyzed,and the weight value is obtained.Secondly,based on the IE theory and the previous weight value,this paper selects the invulnerability index,constructs the multi-objective planning model of invulnerability based on the maximum overall efficiency of the station,and evaluates the invulnerability of Xiaozhai station by taking Xi’an hub station Xiaozhai station as an example.Finally,according to the evaluation results and IE theory,the countermeasures and suggestions to improve the invulnerability of hub station are put forward.This study is a study on the invulnerability of Xi’an Metro Hub Station,evaluates the invulnerability of the hub station,and puts forward the safeguard measures for the invulnerability of the hub station,which can provide a certain reference for the safe operation of Xi’an hub station,and provide a certain theoretical and practical significance for Xi’an Metro to improve the service efficiency of the hub station.
