地铁隧道盾构施工风险管理研究-以某隧道工程为例(硕士)(论文30000字)
The study on the construction risk of the subway tunnel shield -based on the X tunnel project
摘  要
近年来,随着城市化进程的不断推进以及国民经济的快速发展,城市交通需求量不断增加,现有城市交通基础设施已经无法满足人们的出行要求。为了进一步缩短人们出行的时间,提高人们的生活效率,我国各大城市都开始了大力兴建地铁的浪潮。但是,由于当前国内风险管理意识非常薄弱,地铁风险管理重视程度较低,因此,地铁项目建设以来发生的各类工程事故,造成了极大的经济损失和无法挽回的人员伤亡。
盾构施工是当前城市地铁建设中应用最广泛的一种施工方法,具有保障性高,投资成本低等特点,而且对周围环境影响较小。但是,地铁盾构施工还没有形成完善的风险管理体系,实际施工过程中,人们更多采用事后控制,等到状况发生之后才反应过来,再去采取措施时为时已晚。
论文通过对地铁盾构风险管理的相关理论,风险识别的具体方法进行了研究,以某地铁4号线二期工程为背景,在对项目现场进行详细调查分析的基础上,从工程特点和范围、设计关键、水文地质条件以及施工组织方案等方面进行了非常全面的分析,由于4号线隧道盾构施工非常复杂,因此,其中涉及到大量的风险评价指标因素。 [资料来源:http://www.doc163.com]
论文通过定性和定量相结合的方法进行风险评估,研究内容主要包括以下几点:第一,绪论研究。阐明本研究的背景与意义,证明本研究具有理论和实践的双重价值;第二,研究现状分析。分国内和国外,对当前地质隧道盾结构风险管理现状进行综述,并进行评价分析;第三,概念与理论研究。对地质隧道盾结构风险管理的相关概念、理论进行归纳整理,为后续的研究奠定理论基础;第四,问题与对策研究。以某实际的隧道工程为例,分析其在地铁盾结构施工风险管理工作中存在的问题,并根据他们的一个实际隧道工程项目,提出施工风险改进与优化措施,并建立保障机制;第五,实施效果观察。对地铁隧道盾结构实施风险管理改进与优化措施所取得的成效进行观察,证明研究成果具有科学性、合理性与操作性,具有推广应用的可行性与实际价值;第六,结论与展望。对本文的研究进行最后总结,并展望未来的研究发展方向。

ABSTRACT
In recent years, with the rapid development of city modernization and the continuous progress of the national economy, city traffic demand is increasing, the traffic infrastructure of the city has been unable to meet people's travel requirements. In order to further reduce people's travel time, improve the efficiency of people's lives, each big city of our country began vigorously to build subway wave. However, due to the current domestic risk management awareness is very weak, the risk management attention degree is low, therefore, all kinds of engineering accidents since the subway project construction, which caused great economic losses and irreparable casualties. [资料来源:http://doc163.com]
A construction method of the city subway construction is the most widely used shield construction, with high security, low cost characteristics, but also has little effect on the surrounding environment. However, the subway shield construction has not formed the perfect risk management system, the actual construction process, people adopt more after control, until the situation occurred after the reaction to come over, to take measures when it was too late.
The theory of risk management of metro shield, the specific methods of risk identification were studied in Wuhan Metro Line 4 of the second phase of the project as the background, based on detailed investigation and Analysis on the site of the project, from the project scope, characteristics and key design, hydrological and geological conditions and construction scheme of Sthe analysis is very comprehensive, as the 4 line of shield tunnel construction is very complex, therefore, which involves a lot of factors of risk assessment index.
Methods the paper combines the qualitative and quantitative risk assessment, the main research contents include the following: first, the introduction of. To clarify the background and significance of this study, this research has proved that the double value of theory and practice; second, the research status analysis. Domestic and abroad, on the current status of geological tunnel shield structure risk management are summarized, and analysis and evaluation; third, the concept and theoretical research. The related concepts, geological tunnel shield structure and the theory of risk management are summarized, which lays the theoretical foundation for the follow-up research; fourth, study on the problems and countermeasures. An actual tunnel project as an example, analyzes its existence in the subway shield construction risk management problem in the work, and according to an actual tunnel engineering of their projects, put forward the construction risk improvement and optimization measures, and establish a security mechanism; fifth, implementation effect. The implementation of risk management measures to optimize the effect observation of subway tunnel shield structure, the research results have proved scientific, rationality and operability, feasibility and practical value of popularization and application; sixth, conclusion and prospect. The dissertation finally summarizes the research and development direction and future. [资料来源:http://Doc163.com]
