Abstract：
As a proven technology for advance geological forecasting, the TSP (Tunnel Seismic Prediction) system has been used extensively in tunnel construction. This paper briefly describes the working principles and procedures of the TSP system in advance geological forecasting and summarizes various factors that affect TSP forecasting. Furthermore, based on the analysis of numerous measured data and typical cases, a study was carried out regarding the problems relative to data collection, processing, and interpretation. Corresponding countermeasures to improve the reliability of advance geological forecasting are put forward, which may be used as a reference for accurate advance geological forecasting in the future.
