Research on tunnel geo-radar and numerical simulation under complex geological conditions
This study focuses on deploying ground-penetrating radar to explore beneath the earth's surface within compli-cated geological conditions when digging tunnels.The paper begins with analysis of the effects of complex ground condi-tions on tunnel construction is followed by an exploration into how ground-penetrating radar significantly aids in examining the geology of tunnels,in addition to the advantages that computational simulation techniques offer in dealing with complex geologic puzzles.At the theoretical level,the basic principle and data processing method ofgeological radar are expoun-ded,and the influence of size factor on target is studied by using gprMax software to design experiments.In addition,combined with the case of Zijinshan No.3 tunnel project in Yongzhou,Hunan Province,this study uses geological radar to collect data andverifies the results of numerical simulation.Specifically,in this case,the geological radar technology is successfully used to predict the fault fracture zone and the fault drop in front of the tunnel face,which provides valuable reference and support for engineering practice.These findings not only deepen our understanding of the application of geo-logical radar in tunnel exploration,but also provide practical early warning and detection means for tunnel engineering un-der complex geological environment.
