Método de procesamiento y adquisición de señales sísmicas durante la construcción de un túnel

摘要

Method for acquisition and processing of seismic signals during tunnel boring that envisages the use of a plurality of pilot sensors (P1, P2, etc.) suitably distributed on the head of the boring machine for the purpose of identifying as accurately as possible the point or points of generation of the seismic signal/noise produced by the interaction of the TBM with the rock. The signals detected are then windowed and compared with at least one recording taken at a suitable distance by means of at least one geophone (G1, G2, etc.) or by means of a vibration sensor on the machine itself in order to detect the signals of seismic vibration that are propagated through the rock by being reflected and/or diffracted within it.
