【摘要】：2008年金融危机爆发,全球经济发展受到制约,增长速度减缓。为保证我国实体经济的安全过度及平稳增长,国务院提出大力发展高速铁路等基础设施建设的中长期规划,而京津城际铁路延伸线作为京津城际铁路的路段,受到了广泛关注和重视。本文以京津城际铁路延伸线为研究对象,对其施工地质环境及特点进行分析,得出其与其他建设项目的不同之处,提出对其软土层大直径泥水盾构施工风险进行管理的研究主题。首先,对研究背景、意义以及风险管理国内外研究现状进行了阐述,并在此基础上,提出本文的研究内容、方法及技术路线。其次,对施工风险管理相关理论知识进行梳理,为后续施工风险管理奠定理论基础。然后,以软土层大直径泥水盾构项目为施工风险研究对象,采用初始风险清单法、专家调查法和现场调查法对其施工风险进行识别,并在此基础上,采用模糊网络分析法对其施工风险进行评估。然而,京津城际铁路延伸线软土层大直径泥水盾构施工风险评估结果较低离不开有效的施工风险控制。因此,文章最后针对软土层施工安全风险和技术风险通过制定有效控制措施进行有效规避,针对质量风险则采用流程控制,从工艺设计到施工,最后到养护形成整体质量风险有效控制措施,而针对经济风险、组织协调风险和管理风险则是通过建立施工风险控制体系,完善施工风险控制制度,制定施工风险控制措施和控制应急救援预案加以有效规避。最后,对本文所做工作及未来研究方向进行了总结。
[Abstract]:In 2008, the financial crisis broke out, the global economic development was restricted, the growth rate slowed down. In order to ensure the security of the real economy of our country excessive and steady growth. The State Council has proposed a long-term plan for the development of high-speed railway and other infrastructure construction, while the Beijing-Tianjin Intercity Railway extension is the link of Beijing-Tianjin Intercity Railway. This paper takes the Beijing-Tianjin Intercity Railway extension as the research object, analyzes its construction geological environment and characteristics, and finds out the difference between the project and other construction projects. Put forward the soft soil layer of large diameter muddy water shield construction risk management research theme. Firstly, the research background, significance and risk management research status at home and abroad are described, and on this basis. Put forward the research content, method and technical route of this paper. Secondly, comb the related theoretical knowledge of construction risk management, lay a theoretical foundation for the follow-up construction risk management. Then. Taking the large-diameter mud-water shield project in soft soil as the construction risk research object, the initial risk list method, the expert investigation method and the field investigation method are used to identify the construction risk, and on this basis. Fuzzy network analysis method is used to evaluate the construction risk. However, the construction risk assessment results of the Beijing-Tianjin Intercity Railway extension line in the soft soil layer with large diameter mud water shield are relatively low. Therefore, effective construction risk control is necessary. Finally, aiming at the safety risk and technical risk of soft soil construction, effective control measures are established to avoid effectively, and process control is used to control quality risk, from process design to construction. Finally, the maintenance of the overall quality risk effective control measures, and in view of economic risks, the organization of risk coordination and management risk through the establishment of construction risk control system, improve the construction risk control system. Make construction risk control measures and control emergency rescue plan to be effectively circumvented. Finally, the work done in this paper and the future research direction are summarized.
