subterranean tunnel construction of highways, railways, and hydraulic power projects.However, tunnel geological prediction becomes a difficult problem with high demand and difficult technology. Geological problems concerned in tunnel geological prediction include structurally weak zones, aquosity, and rock mass engineering classification. It is especially difficult to make geological predictions for hydrous fracturing, caving, and loose bodies.There is limited observation space inside the tunnel, which increases the difficulties for advancing the precision of velocity analysis using seismic reflection data and reflector positioning and determining the rock mass behavior. Different geological objects have different physical properties. The differences in structural properties and crush state of the rock mass result in differences in the mechanical properties, while different water saturations result in different resistivity. Thus, it is difficult to cover two physical properties with one geophysical prospecting method. The seismic method mainly prospects the
