GPR is the most commonly methodmethodfor tunnel geological prediction.It can quickly
efficiently and non-destructively detect the surrounding rock geological conditions within about 30 meters in front of the tunnel face. First
introduces the working principle of the ground penetrating radar in this paper
GPR is applied to tunnel geological prediction in Langqi.The radar data result map is analyzed and the effective solution for the tunnel excavation is provided. This work provides areference for the subsequent similar engineering detection.
