Amberg Measuing Technique Ltd. (Switzerland) has developed the newly TSP 203 plus system and patented the compact, which is a tunnel seismic prediction equipment. It was specially designed for tunnel geologic advanced prediction. This paper introduces the technical characteristics and basic principle of advanced geological prediction. Based on the application examples of Longtan tunnel of Hu-Rong Expressway, the system's practicability, believablity and the important effect in directing the construction of the project, are analyzed in detail.
