Research On Green Evaluation On Utility Tunnel Based On Fuzzy Comprehensive Evaluation Method

The underground urban utility tunnel can intensively manage various municipal pipelines and save urban space resources.Therefore,it has been the trend of future municipal infrastructure construction.In this context,it is of great practical significance to evaluate whether the utility tunnel is environmentally friendly during construction,explore how to evaluate the greenness of the utility tunnel and carry out green evaluation on utility tunnel under the current concept of sustainable development and low carbon environmental protection.At present,the research on the utility tunnel mainly focuses on its financing mode and construction process.The object of research on green evaluation is mainly residential and public buildings.This study mainly carries out green evaluation on utility tunnel,and determines the index weight by combining the analytic hierarchy process(AHP)with the entropy weight method through the establishment of the green evaluation index system for the utility tunnel.Finally,the fuzzy comprehensive evaluation method is used in the evaluation.First of all,the status quo of the construction and research of utility tunnel and green evaluation at home and abroad is analyzed.On this basis,the related concepts and theories of utility tunnel and green evaluation are expounded,including the concept,type,construction principles,existing problems and the concept of green evaluation of utility tunnel.Furthermore,the contents of the green evaluation for utility tunnel are explained,thereby laying a solid theoretical foundation for the subsequent research.Secondly,the factors affecting the green evaluation for utility tunnel are analyzed.On this basis,the green evaluation index system and evaluation criteria for utility tunnel are established by referring to the green building evaluation indicators at home and abroad and combining with the characteristics of utility tunnel.The weight of index is determined using the combination weighting method integrating the analytic hierarchy process and the entropy weight method.Next the evaluation is carried out using the fuzzy comprehensive evaluation method.Finally,the evaluation model is verified based on an established utility tunnel project,and some improvement measures and recommendations are put forward by analyzing the problems through conclusions.The study on the green evaluation for utility tunnel enriches the research contents of the green construction of utility tunnel and is helpful to deepen the awareness of "green" construction in practice,which is of certain reference for the green construction of utility tunnel in the future.
