Application of the TSP 203 system in geological advanced prediction of YuanMo expressway tunnel
Wen Shu · Progress in geophysics · 2003
Amberg Measuring Technique Ltd.(Switzerland) has developed and patented the compact, newly TSP 203 system, which is a tunnel seismic prediction equipment. It was specially designed for tunnel geologic advanced prediction. The TSP 203 system is excellent intelligentized in data acquisition, processing and evaluation. This system can predict at least 100m in ahead of the tunnel face where the kinds, locations and sizes of geologic blocks, and evaluate rock mechanical parameters. For this reason, it can confirm the evidence for reasonable timbering parameters, and ensure the quality and safety in tunnel operations. Applications of the TSP 203 system in YuanMo express tunnel are presented in this paper.
