摘要
不良地质的准确预测是深埋长大隧洞TBM安全高效施工的重要保障,文中针对TBM施工深埋长大隧洞不良地质探测难题,以新疆某引水隧洞项目为研究背景,依据三维地震波法和三维激发极化法探测技术原理,提出了相应的综合超前地质预报实施流程,成功实现了TBM隧洞掌子面前方不良地质的准确预测,并通过TBM隧洞51+052里程现场探测对实际开挖揭露情况进行了验证。研究成果为类似工程施工提供了参考。
The accurate prediction of bad geology is an important guarantee for the safe and efficient construction of deep long tunnel TBM.Aiming at the difficult problem of bad geological detection of deep buried long tunnel in TBM construction,this paper takes a diversion tunnel project in Xinjiang as the research background,and puts forward the corresponding comprehensive advance geological prediction implementation process according to the detection technology principle of three-dimensional seismic wave method and three-dimensional stimulated polarization method,and successfully realizes the accurate prediction of bad geology in front of the face of the TBM tunnel.It is verified by field detection of 51+052 miles of TBM tunnel and actual excavation disclosure.The research results provide a reference for the construction of similar projects.
