Abstract：At home and abroad,during the process of the channel tunnel construction, TSP has been used to detect small structures such as fault, collapse column.Because the fault plane and collapse column interface is undulating, the received energy of the reflected wave is weak, therefore it is difficult to image ahead of the tunnel. The scattered topography method based on Huygens-Fresnel principle can take full advantage of the information of the full wave field seismic signals. Scattered wave offers a new image method for TSP due to the good migration effect. In this particle, Building exploring tunnel model to study the effect of scattered topography, and prove the feasibility of the scattered topography used in the TSP.
