盾构机始发与接受的风险源分析及其控制措施

Risk Analysis and Control Measures of Initiation and Acceptance of Shield Machine

盾构法隧道施工以机械化程度高、安全程度高、作业环境好、施工进度快等优点广泛应用于城市轨道交通区间隧道工程中。同时,盾构始发与到达时掘进工序中隧道建设过程中处于关键地位,直接关系到既有建筑物和新建隧道的安全,但该阶段也是施工过程中最容易出现问题的阶段。为此,依托深圳地铁7号线车公庙-上沙站区间盾构法隧道工程,阐述了盾构机始发与接受的风险源和有效的控制措施,为类似工程提供了重要参考。

Shield tunneling has the advantages of high degree of mechanization,high safety,good working environment and fast construction schedule.It is widely used in urban rail transit tunnel engineering.At the same time,the tunnel is the key position in the tunnel construction process,which is directly related to the safety of existing buildings and new tunnels.However,the stage is also the most prone to problems in the construction process.To this end,relying on the Shenzhen Metro Line 7 Che Kung Temple-Shang Sha Station section shield tunneling project,describes the shield machine origin and acceptance of the risk source and effective control measures for similar projects to provide an important reference.
