Determination of optimal trace for tunnelling of underground (buried) services under a road:

The prospection GPR and SRS result for the tunnelling optimal trace determination

On the right side figure there is an example of geological-gephysical section accordig to GPR and SRS results. There is the optimal tunelling trace and workability of the rock (according to rock velocities by SRS, in terms of ČSN 733050) marked by red and violet colors.
