An Application of Comprehensive Geological Prediction Methods in a High-Speed Railway Tunnel

The tunnel involved in this study is a double-track tunnel with a 4113m length and 390m maximum depth which is currently under construction. By analyzing the specific engineering geological and hydro geological conditions and summarizing the past geological prediction techniques, the comprehensive geological prediction methods are adopted in the project, and the accuracy and feasibility of the theory and techniques are verified in the practical construction process. It is concluded that the comprehensive geological prediction methods are conducive to reduce the risks, accelerate the schedule and guarantee the quality of the construction, and provided a good guidance and reference for the tunnel constructions of this kind
