Study On Green Construction Technolongy And Evaluation Method Of Shenzhen Metro Line 9 Open Cut The Station Project

In order to alleviate the pressure of urban traffic and accelerate the rapid development of urbanization,many cities in China begin to conduct the subway construction quickly.During the process,an amount of resources and energy will be consumed,and it may cause some environmental problems.Currently in our country there are few researches on technology and evaluation on the green construction of subway.Meanwhile,the concept of subway green construction is also relatively blurred to the constructors.Because of those reasons,it is of great practical significance to study the technology and evaluation method of the open-cut subway station green construction.The paper carries out the following researches with the combination of Shenzhen Metro Line 9 open-cut station project:(1)Based on the "Four Environmental Protection" principle,the research classifies green construction technology of Shenzhen Metro Line 9 and analyzes its economic,social and environmental benefits during the construction process.(2)Through the large number of literature reviews,main influence factors of construction management,environmental protection and resource conservation indicator in the green construction evaluation system are analyzed.What's more,the hierarchical structure model of the green construction evaluation indicator factor is established with the analytic hierarchy process(AHP).(3)By the Delphi method,there is a comparison between the importance and hierarchy of the green construction evaluation indicator factor.Through which the judgment matrix of the indicator factor can be constructed,and the indicator weight can be obtained with the mathematical method.Together with the research of green construction evaluation indicator standard,the evaluation system on green construction of open-cut subway station can finally be formed.(4)The green construction evaluation method of the subway project is determined,and the green construction evaluation result is divided into four grades,namely,excellent,good,qualified and unqualified.Relying on line 9 open cut station engineering,makes an analysis of the effect of green construction,it is concluded that the Shang Meilin,Mao Ling,Ni Gang stand post station,Lu Dan village station,the grand theatre five evaluation results of stations,respectively,a good and qualified.
