Means have a tunnelling machine by correlation between measurements carried on the tunnel boring machine, and data coming from the surface of surveys

摘要

The present invention relates to a tunnel boring machine (1) comprising a cutting head (5) provided with tools for working (3) of the terrain in which a bore of the tunnel, comprising a set of probes (6) providing the measurements to the computing means (4) provided in order to establish correlations from said measurements (m) and of the data from the surveys and / or measurements of deformation of the ground from the surface, and to determine information on the ground during excavation, by comparison between said measurements (m) and the correlations.
