Evaluation of Railway Green Construction Scheme Based on Interval Number Attribute Connection Degree

摘要

Railway green construction is one of the important measures to realize the sustainable development of railway. At present, the research on the evaluation standard of railway green construction is still in the exploration stage. Based on the "green construction evaluation standard of construction engineering", considering the characteristics of railway construction On the basis of this, an evaluation method of railway green construction scheme is put forward, and the evaluation of green construction scheme is realized. With reference to the relevant green construction standards and domestic and foreign research results, to build the railway green construction stage evaluation index system. The interval range of the index is determined by the interval hierarchy analysis method. Secondly, the index interval is transformed into the interval number matrix, and then transformed into the contact number matrix, and the interval multi-attribute railway green evaluation based on the number of links is established, model. The model determines the relative proximity of each green construction scheme by calculating the final comprehensive contact number, and determines its merits by sorting. Finally, through the example verification, the optimal green construction scheme of intercity railway of Lanzhou to Nakagawa Airport is obtained. The advantage of this method is that it is more reasonable to use the interval number to describe the possible range of the index than the simple numerical representation, so that the evaluation result is more accurate and more reference. In recent years, China's economic and social development of good and fast, the railway as a major artery of the national economy, the state's important infrastructure and popular transport, its backbone position has become increasingly prominent. In order to realize the sustainable development in the course of railway construction and promote the construction of resource - saving and environment - friendly railway, we must pay attention to the application of "green" technology in railway construction. To this end, as soon as possible to establish China's green railway evaluation standards for the standardization and guidance of modern railway construction, will become the inevitable development of China's railway industry and needs. At present, there are few researches on the evaluation of high-speed railway construction from green angle, and the evaluation theory and methods need to be improved constantly. Xiong Feng and so on to explore the necessity of sustainable development of green railway; Ding Leilei and so on to Beijing-Shanghai high-speed railway as the research object, the basic theory of green development to sort out, and based on green theory and high-speed railway construction link to evaluate its green development level; Bao Xueying and so on "green construction evaluation standards" Based on the deep consideration of the characteristics of green railway construction, this paper puts forward a kind of evaluation method of railway green construction grade, realizes the evaluation of railway green construction grade, provides technical support for standardizing the construction of domestic railway green; Zhang Junqiang Multi-model integrated green construction scheme evaluation method, the green construction program for the merits of the evaluation study. At present, scholars in the railway green construction program evaluation method put forward a lot of innovation. Green construction program is to guide the railway green construction technology and guidance documents, is to create the whole life cycle "green railway" an important part of its advantages and disadvantages of the implementation of green construction has a decisive role, related to the advantages and disadvantages of green construction evaluation The To evaluate the construction plan of the green railway, we must first determine the weight of the evaluation index system. At present, the mature sub
