【摘要】：随着我国经济的不断发展,城市化进程进一步加快,地铁的发展成为了我国各大城市解决交通拥挤问题的首选方案。地铁区间隧道的建设大多数采用盾构法进行施工,而土压平衡盾构又是盾构法应用最广泛的的一种。因为它适合在城市密集的地方作业,这也恰好适应了城市地铁的建设要求。但是地铁隧道盾构施工的风险管理仍然是一个沉重的话题,目前我国的地铁隧道盾构施工风险管理尚处于起步阶段,项目管理者风险意识淡薄,风险管理能力较差,为此在现阶段对工程项目风险管理进行深入研究势在必行。论文首先分析了国内外关于隧道施工风险管控存在的问题,再结合地铁隧道盾构施工的特点,首先介绍了风险的定义、特点,结合南京地铁三号线天元西路站-清水亭西路站区间工程实例,针对该工程的特点、重点及难点,按照风险管理的整个过程,从风险辨识到评估,做了重点的分析和系统的分类。特别是对风险控制措施,从施工、地面建筑物、地下管线、管理四方面做了系统的梳理和分析,并提出了应对措施。通过本文对地铁土压平衡盾构法施工风险管理的研究,能够较好地预测和解决施工中可能遇到的问题,对保证施工安全具有一定的指导意义,也对于我国的地铁建设有着一定的参考作用。
[Abstract]:With the continuous development of China's economy, city to further accelerate the process, the development of the subway has become China's major city to solve the traffic congestion problem of the preferred solution. Most of the subway tunnel construction with shield method construction, and is also the shield earth pressure balance shield method is the most widely used kind. Because it is suitable for in the city where intensive operations, it also fits the requirements of the construction of city subway. But the risk management of shield construction of subway tunnel is still a heavy topic, the current risk management of metro tunnel construction in China is still in the initial stage, the project management risk consciousness, risk management ability is poor, so in the present the stage of engineering project risk management research is imperative. It firstly analyzes the problems about the existence of risk control of tunnel construction at home and abroad, combined with the subway tunnel Channel characteristics of shield construction, firstly introduces the definition of risk, characteristics, combined with the Nanjing metro line three Tianyuan Road Station - Water Pavilion Road station interval project, according to the characteristics of the project, emphases and difficulties, in accordance with the whole process of risk management, from risk identification to assessment, made a classification analysis and key system the. Especially on the risk control measures from construction, ground buildings, underground pipelines, four aspects of management to do a systematic analysis, and puts forward the countermeasures. This paper on the pressure balance shield construction risk management of underground soil, can predict and solve the possible problems in the construction to ensure, which has a certain guiding significance to construction safety, but also for the subway construction in China has a certain reference value.
