The Green Construction Based On Fuzzy Matter-element Evaluation Research

In the next five years,the subway construction in China will peak.However,because the subway project has long cycle,high cost and complex correlation factors,in the construction process requires a lot of resources and energy,and at the same time produce waste water,waste gas,solid waste,dust,waste residue,noise pollution,and environmental security around to bring huge risk.In the concept of “sustainable development”and “green”concept gradually in-depth today,build green subway has become a consensus in today's society.Implement green subway engineering construction is an important part of the whole life cycle of construction,ensure the subway as small as possible in the process of the construction environment,the influence of maximum saving resource is the important content of the green subway is important embodiment of the concept of sustainable development in green subway construction.In this paper,based on domestic and foreign literature study,on the basis of analysis,the paper discussed the related theory of papers.Respectively introduces the subway construction,green construction and green construction assessment and fuzzy matter-element theory,and analyzes the current status and continuous improvement measures for metro green model.Secondly,based on the characteristics of the green construction theory and the subway project,preliminary target decomposition method was used to construct the index system.And using the method of theoretical analysis and expert opinion to optimization of index system,established the evaluation index system of the green construction.Again,the paper analyzes the fuzzy matter-element theory for feasibility evaluation of metro green construction,build the metro green construction based on the fuzzy matter-element evaluation model,and using fuzzy analytic hierarchy process to calculate the weight of each index.Finally used to build the index system and evaluation model of engineering of xi 'an subway line 4 project is evaluated,and the corresponding improvement measures are put forward based on the evaluation results.As can be seen from the evaluation results,this paper established the index system and evaluation methods of the reasonable and feasible,through evaluation can accurately reflects the level of green construction of metro project,and find the actualprocess of construction of the key factors influencing the level of green and existing problems of environmental pollution,resource waste,for subway construction has a certain practical significance and reference value.
