3D-seismic test measurement
The Asse-GmbH carried out a three-dimensional (3D) seismic test measurement on behalf of the Federal Office for Radiation Protection (BfS). For this purpose, a company that had to be commissioned had to get the approval of the property owners affected (permit to enter).
Measurement process
In the test measurement, the excitation and geophone points were at first measured, installed and connected through a cable network. Vibrators that had been attached to specially designed vehicles produced the seismic signals (vibrations).
Once the test measurement had concluded after about two weeks, the geophones and cables were dismantled and the properties were brought back to their original condition.
Results of the test measurement
At first, only field data were determined in the test measurement, which were subsequently evaluated by experts with a special software. Only after all tests have been carried out could it be decided as to whether and to what extent it will be reasonable to carry out a main measurement.
