无水砂卵石地层地铁盾构施工风险管理

Risk Management of Metro Shield Construction in Anhydrous Sand and Pebble Stratum

随着城市化的发展,人们对地铁行业的需要越来越高,地铁项目建设同样也引起了高度关注。地铁项目建设离不开盾构施工,地铁盾构施工自动化程度高,能提高施工效率,应对复杂环境,但也存在安全风险因素,其中,盾构施工的安全风险管理是非常重要的环节,在地铁盾构施工的安全风险管理的过程中,必须考虑施工风险管理存在的安全问题和采取何种措施进行风险管理。本文分别从风险识别、风险评估、风险评价及风险控制几个方面对盾构施工风险管理进行了研究,结合乌鲁木齐地铁一号线无水砂卵石地层盾构施工过程,提出一系列无水砂卵石地层地铁施工风险的管理措施,以期为相关地铁盾构施工风险管理提供工程经验。

With the development of urbanization, People’s travel is more and more needed, and the construction of the subway has aroused widespread public concern. The shield construction method will be used in subway construction, which is efficient and automated in a complex environment, but there are certain risk factors, so safety risk management is very important. When risk management is carried out, the safety problems existing in construction and the measures to be taken should be taken into account. This paper discusses the risk management of shield construction from four aspects of risk, combined with the shield construction process of anhydrous sand and pebble stratum in Urumqi Metro Line 1, which provides practical experience for relevant construction risk management.
