摘要

为避免或减小TBM隧道在施工过程中遭遇围岩坍塌、突水突泥等地质灾害，基于搭载于TBM的破岩震源和激发极化超前地质预报系统，对TBM环境综合超前地质预报方法进行研究，以实现掌子面前方不良地质定位。在探明不良地质的基础上，提出施工动态管理方法，以实现对不良地质的超前治理，进而有效避免地质灾害的发生。通过工程实践表明：提出的搭载于TBM综合超前预报系统可以有效探明掌子面前方的不良地质，采用的动态施工管理方法可有效对不良地质灾害进行防控，确保TBM安全、高效地施工。

Abstract

In this study, to reduce or even prevent geological hazards, such as surrounding rock collapse, water inrush, and mud outburst during TBM tunneling, a comprehensive advanced geological prediction system based on TBMcarried rockbreaking seismic source and induced polarization is evaluated to accurately locate the adverse geology position ahead of the tunnel face. Thus, dynamic construction management methods are put forward to perform the advanced treatment of adverse geology and effectively prevent the occurrence of geological disasters. The engineering practice demonstrates that the proposed comprehensive advanced prediction system can effectively detect the adverse geology ahead of the tunnel face, and the dynamic construction management can successfully reduce or even prevent adverse geological disasters, ensuring a safe and highefficient TBM tunneling.

Key words： Gaoligongshan tunnel; TBM; comprehensive advanced forecast; adverse geology; construction management
