PROCESS AND DEVICE FOR MONITORING THE APPEARANCE OR THE SPREAD OF FRACTURES OR CRACKS IN MATERIALS, PARTS, COMPONENTS, STRUCTURES OR FLYING OBJECTS, ESPECIALLY IN AREAS SUBJECT TO EARTHQUAKES OR DURING LAND MOVEMENTS DURING THE CONSTRUCTION OF TUNNELS. |
| abstract |
A method and device for monitoring the occurrence of cracks, fractures, earthquakes and landslides take advantage of the fact that such events are associated with the occurrence of variations in electric fields. These variations are recorded by means of a field probe (1) which comprises metallic probe elements (2, 3) which supply a differential amplifier (5) whose output signal (69) is transmitted to a evaluation (10, 11). |
