|
 | The subject of this paper is the description of the recent developments of our already improved pulsed eddy-current test device. Depending on defect depth and size, it has been shown that depth detection limits of about 8 to 10 mm can be obtained in austenitic components. The use of current pulses with high peak values (up to 10 A) makes it necessary to design adapted probe coil arrangements. These probes ... |

|
| The geotechnical results and experiences from several tunneling projects carried out in different geological units are discussed. Essential for the successful use of tunneling machines in the first place is the stability of the rock. Because of the high economical expenses detailed engineering geological investigations with exact predictions are provided. By means of the experiences gained, a classification of rocks for the use of tunneling machines is suggested. (AA) |
