高速铁路隧道工程精益化建设管理关键技术

Key Techniques for Lean Construction Management of the High Speed Railway Tunnels

施工技术复杂多样、不可预见风险因素多和所处不良地质复杂多变是制约高速铁路隧道安全高效建设的主要因素,要实现隧道工程的高效建设,就要提高隧道建设管理模式和信息化应用水平。基于此,文章首先研究提出高速铁路隧道精益化建设管理应用模式;然后重点深入研究BIM、超前地质预报、隧道围岩量测、三维断面扫描等关键技术在高速铁路隧道工程精益化建设管理中的深度融合应用,并研发了轻门户移动端和云服务信息管理系统;最后结合工程实际应用进行验证,实现了对隧道工程建设中重难点风险源监控、关键任务红线管控和安全质量问题的有效管理,有效地提高了各参建单位协同作业效率,达到了精益化建设管理目标。

Improvements of management mode and application level of informationization techniques are the key factors to safe and efficient construction of the high-speed railway tunnels considering the complexity and diversity of construction techniques,unpredictable risk factors and varied geological conditions.In the paper it proposed a management mode for lean construction of high-speed railway tunnels,studied the in-depth integration and application of key technologies of BIM,advance geological prediction,tunnel surrounding rock measurement,3D laser scanning,etc.in the lean construction management of high-speed railway tunnels,and developed the light portal APP and cloud-based information management system.Through the verification of practical engineering application,it realized good monitoring of key risk resources in tunnel construction,redline control for key tasks and effective management of safety and quality,increased efficiency of collaborative operation of all parties involved and reached the goal of lean construction and management.
