Application of Tunnel Seismic Image Approach to the Advanced Geological Prediction for Tunnel

With the large-scale construction and rapid development of underground engineering, a large number of underground engineering construction, such as tunnel and subway emerged. The geological structure of the tunnel is complex and the roc is fragmented. Tunnel seismic image is a new geophysical technique. This method has advantages such as high resolution, high reliability and obvious image characteristics. Therefore, to insure the safety of the construction and to eliminate geological disasters, the advanced prediction technology of seismic image in tunnel detection is applied. In the paper, the seismic image was used to detect the Huangzhuang tunnel geological condition. The reflected waves, the refraction wave and the surface waves can reflect the same geological conditions, and the result is in accordance with the drilling. Tunnel seismic image can effectively and safely guide the excavation of the tunnel section working surface in combination with reconstructed images and excavation technology.
