复杂地质盾构隧道安全管理与风险防范对策

Safety Management and Risk Prevention in Shield Tunneling under Complex Geological Conditions

复杂地质条件下盾构隧道施工安全管理和风险防范贯穿于施工阶段的全过程,以武汉市轨道交通二号线越江隧道工程盾构区间隧道施工为例,从地质工作和环境调查、盾构选型及细节功能设计、施工方案制定和优化、风险管理、标准化作业、关键工序节点验收和内控等方面,阐述了复杂地质盾构隧道安全管理的重点和风险防范的对策,较详细地介绍了越江隧道施工过程中的成功经验。

Safety management and risk prevention exist in the whole course of the construction of shield-bored tunnels under complex geological conditions. The key points of safety management and risk prevention of river-crossing shield- bored tunnel on line 2 of Wuhan Metro are discussed in term of geological conditions, environment investigation, shield type selection and detailed functional design, construction program determination and optimization, risk control, stand- ardized construction and control and test of key construction points.
