Research on the Application of 3D Comprehensive Advanced Prediction in Tunnel Fault Fracture Zone
The fault fracture zone inside the tunnel is a highly hazardous geological body,whose precise detection during construction has always been a key and difficult point in advanced geological prediction of tunnels.To effectively prevent accidents such as tunnel collapse,water inrush,and mud gushing caused by fault fracture zones,a three-dimensional comprehensive detection method based on TGP method,transient electromagnetic method,and geological radar method is proposed and applied on actual tunnel engineering,which achieves good detection results.The results show that:1)The comprehensive advanced prediction method formed by the optimized combination of TGP method,transient electromagnetic method,and geological radar method can not only effectively improve the accuracy of detection,but also obtain more comprehensive geological information;2)The use of three-dimensional detection and visualization technology can more intuitively and accurately display the development scale,properties,and spatial relationship with the tunnel of the fault fracture zone,providing more vivid prediction results for tunnel construction.
