摘要
TBM对不良地质条件适应能力差,因此需要对TBM隧洞前方地质条件具有较高准确性和可靠度的超前地质预报方法。本文以新疆某TBM隧洞施工现场为例,采用三维地震波法对掌子面前方的不良地质进行探查,其围岩揭露状况与探测结果一致,证明在三维地震波法是一种适合TBM隧洞前方不良地质探查的高效手段,可为TBM隧洞工程施工提供参考和指导。
TBM is hard adaptive to poor geological conditions.advanced geological prediction methods with high accuracy and reliability are required for the geological conditions ahead of the TBM tunnel.The paper,taking a TBM tunnel construction site as an example in Xinjiang,the 3D seismic wave method is used to probe the unfavorable geology in front of the face.The surrounding rock exposure is consistent with the detection results,which proves that the 3D seismic wave method is suitable for the unfavorable geological exploration in front of the TBM tunnel,it can provide reference and guidance for similar projects.
