Key Construction Technology Research And Risk Control Of A Metro Station In Wuhan

With the development of economy,people's demand for the new way of transportation is increasing.Although compared with the developed countries,the construction of the subway in China started relatively late,but after many years of construction and development,it has gradually formed a theoretical approach to the national conditions.Subway is not just as a simple means of transport,subway station construction and even the city's own label,to some extent reflects the city's cultural history,customs.Although the construction of the subway has brought a series of benefits,but as a huge underground project,but also brought a lot of security risks,resulting in a lot of security incidents.Through the study of many engineering cases found that in fact many risks and is not a personal understanding of the inevitable,if in the daily construction to intentionally pay attention to these risks,take measures in advance to prevent,can greatly reduce the probability of accidents.With the continuous improvement of technology,the standardization of management and scientific,more advanced equipment,will greatly reduce the duration,thereby reducing costs,the entire project will move towards a more orderly development.This paper mainly studies the key construction technology of metro station with open cut method.In the beginning,the background and significance of this thesis are briefly summarized,and the present situation and development of metro station construction are introduced.From the technical,institutional,equipment and other aspects of the promotion to strengthen the construction of the subway station management,to ensure that the construction process more standardized standards.Then introduced the engineering risk and the subway station construction related theory knowledge,the purpose is for the following research and analysis for theoretical guidance.Then,taking the Wuhan subway Square Street Station as an engineering case,this paper introduces the hydrogeology,surrounding environment,climate and traffic of the project.Emphasis is laid on the study of excavation,support and construction of the main part of the subway station with open cut method.Finally,the Lec assessment method is used to analyze the key risk sources existing in the open cut metro station,determine the risk grade and formulate corresponding risk control measures.Through the establishment of risk control measures,it can effectively reduce the occurrence probability of Engineering accidents.Ensure the construction of the station can be carried out smoothly,safely and efficiently.Meanwhile,it can also be used as a reference for the similar projects.
