| Abstract: | Ground Penetrating Radar is very perfectly when we use it to make prediction of rock structure in front of face during tunneling of expressway. Because forecast about rock structure in front of face about tunnel during tunneling, using Ground Penetrating Radar, has the advantage of high speed and accuracy. At the same time, all data, which we get in field, can be dealt with and displayed in time. In this paper the authors give an example of Bajiaoxi Tunnel in Shaoyang-Huaihua Section, of Shanghai-Ruili expressway in Hunan by the GPR combined with TSP203 and geological line drawing in face of tunneling, with accuratel information about the rock structure in front of the face of tunneling presented for Bajiaoxi Tunnel. This information is very important in arranging the tunneling method and reducing the risk of work during the process of tunneling. |
