Abstract: During the tunnel construction，uncertainty of forward geological condition leads to incipient faults of construction and geological disasters. Thus，it is significantly necessary to study geologic prediction. This paper not only introduces the basic principle，data collection and data analysis of tunnel seismic prediction(TSP) system，but also presents its application to the construction of Yinzuiyan Tunnel. Through the comparisons among geological analysis，result of TSP system and the actual situation，the advantages of TSP system are proved，such as accuracy and fast prediction speed. Besides，some shortages of TSP system are summarized.
