Integrity assessment of ground anchorages |
摘要 |
A method and apparatus for monitoring the condition of a ground anchorage including a tendon arranged in a bore in a group formation at a site is characterized by detecting the vibrational response signature of the anchorage to an impulse load. The vibrational response signature to the impulse is recorded and compared with a reference signature from which any changes in the integrity of the anchorage can be determined.
