Abstract: With the development of tunneling engineering, the number of tunnel projects gradually increase with long distances, deep burial depths, and complicated geological conditions, therefore safety problems of the construction also increase. Advanced geological prediction is a key guarantee for the safety of tunnel construction. Researchers all over the world have carried out theoretical analysis, model simulation and experimental research to improve the accuracy of geological prediction. In this paper we summarize the research progresses of advanced geological forecasting techniques, such as geological analysis methods, seismic wave methods, electromagnetic methods, and electrical methods. We analyze the principles as well as advantages and shortcomings of these methods, and discuss the advanced geological prediction technology within TBM construction process. We propose a comprehensive geological prediction system based on five principles: combining geological survey and geophysical prospecting; combining long, medium and short distances; considering both inside and outside of the tunnel; integrating qualitative and quantitative analysis; incorporating empirical method and expert system analysis. Moreover, we discuss the research focus and future directions with seismic interference method in the purpose of offering reference for promoting the application and development of advanced geological prediction technology in tunnel engineering.

Key words: tunnel engineering, advanced geological forecast, integrated geological forecast method, seismic interferometry, TBM construction
