Evaluation Of Subway Green Construction Based On Combination Weighting Of Game Theory And Grey Two-tuple Linguistic

At present,China’s subway construction has entered a period of high quality and high development.However,the problems of resource and energy consumption and eco-environment degradation caused by extensive construction are becoming increasingly serious.With the concept of green development put forward,green construction has become an important embodiment of sustainable development concept in subway construction.This paper conducted research on the evaluation of subway green construction,aiming to promote the development of green subway construction,and the construction of resource-saving and environment-friendly subway.Firstly,the concept of green subway construction was briefly discussed,and the implementation principles and key points of green subway construction were also analyzed.In addition,according to the characteristics of subway construction,the purposes and principles of subway green construction evaluation were clarified.On this basis,an evaluation index system of green construction was preliminarily established by identifying the influencing factors of subway green construction.The evaluation index system of green construction was optimized by the fuzzy-DEMATEL method,and the key indicators were analyzed according to the importance ranking.Then a systematic and comprehensive evaluation index system for subway green construction was set up,which included 18 evaluation indicators such as water resources saving rate and air pollution control.Secondly,the game theory combination weighting model was used to combine the subjective and objective weights,so as to seek the consistency and compromise between the two weights.Aiming at the fuzziness in the evaluation process of subway green construction,the grey clustering method was extended to the two-tuple linguistic.Then the subway green construction evaluation model based on the combination weighting of game theory and grey two-tuple linguistic was established.The model is convenient for the comparative analysis among various indicators,so as to realize the continuous improvement of subway green construction evaluation.Finally,taking the Qingxiushan Station of Nanning Rail Transit Line 3 as an example,the implementation of green construction during the project construction was systematically analyzed and studied,and the above evaluation model was used to evaluate the green construction.The evaluation grade of the green construction the project was "good".On this basis,the evaluation results were analyzed in combination with the the actual situation of the project,and corresponding improvement suggestions were put forward for energy saving,land saving and material saving.It has been verified the scientific nature and feasibility of the index system and evaluation method established in this paper,which provides new ideas and methods for the evaluation of subway green construction.
