摘要
采用TGP与地质雷达进行超前地质预报,可有效预测隧道岩溶地质灾害。该文总结了TGP与地质雷达对无充填型及充水型岩溶的综合物探响应特征,两者综合分析、相互佐证,提高了预报的可靠性。经超前水平钻探和开挖验证表明,具有较好的预报效果。该文对类似工程具有一定的指导意义。
Using TCP and geological radar for advanced geological forecast can eftectively predict tunnel karst geological disasters.This paper summarizes the comprehensive geophysical exploration response characteristics of TGP and geological radar to non-flled and water-flled karst cave.Through their comprehensive analysis and mutual verification,the reliability of the prediction has been improved.It has been verified that advanced horizontal drilling and excavation have good prediction effect.This paper has certain guiding significance for similar projects.
