Abstract
For deep tunnels, their engineering geological and hydro-geological conditions are highly changeable and complex. Rough construction often triggers or produces accidents, such as water inrush, mud inrush, landslides etc. For informational dynamic design and construction of tunnels, it is of vital importance to carry out advanced geological Prediction. Based on the engineering background of QiYueshan tunnel, a high risk karst tunnel in Livan expressway, combined with seismic propagation theory and TSP geological prediction practices, reflection characteristic of seismic wave for typical geology disaster in karst tunnel is studied. The important results of guiding tunnel construction are concluded. Application effect of prediction techniques is discussed. The scientificity and reliability of Prediction techniques are verified by comparing the prediction results with the practical projects.
