TGP超前预报数据采集关键技术研究

近年来,国内外隧道建设向更深、更长、更大的方向发展,为减小隧道建设过程中突水突泥、塌方等地质危害带来的影响,隧道超前地质预报工作至关重要,TGP超前预报技术则作为国内技术最先进、运用最广泛的代表之一.本文针对TGP数据采集过程中可能导致地震数据质量较差的因素,通过理论分析、正演模拟、工程应用等研究方法,对TGP超前预报数据采集关键技术开展了相关研究工作.最终归纳出了一套适用于大多数隧道工程的TGP超前预报数据采集工作指南,有助于提高TGP预报精度,保障隧道施工安全.

Research on key technologies of TGP advance geological prediction data collection

In recent years,the tunnels we construct at home and abroad have been deeper,longer and larger,the advance geological prediction of tunnel is a very important method to reduce the impact of geological hazards such as water inrush,mud inrush and landslide during tunnel construction,the advanced geological prediction technology of TGP is one of the most advanced and widely used technologies in China.In this paper,based on the theoretical analysis,forward modeling,engineering application and other research methods for the factors that may lead to poor seismic data quality during TGP data collection,relevant research work is carried out on the key technologies of TGP advanced forecast data collection.Finally,a set of TGP advance geological prediction data collection guidelines applicable to most tunnel projects are concluded,which helps to improve the accuracy of TGP forecasting and ensure the safety of tunnel construction.
