Abstract:

Based on the detection principle of TSP,the reason to produce errors of the interface of the inclined stratum predicted by TSP was analyzed. Combined with comparative analysis of engineering examples, the regularity of angle and error of inclined stratum predicted was discussed. The result showed that the  interface  of the predicted  inclined stratum would always appear later than the real interface, which had no relation with the angle between the inclined stratum and the axis of tunnels.

Key words:  tunnel seismic prediction; advanced geological forecast; error; inclined stratum
