Progress in using geophysical methods for foundation quality assurance and inspection

  • Modern geophysical methods might be either directly applied to foundations or integrated into existing testing schemes to assist in quality assurance and inspections. This paper gives an overview on available ideas and some more detailed examples from the author `s work including: - Vibrator technologies to improve pile integrity testing. - Ideas from vertical seismic profiling used in multichannel pile inspection - Cross- and downhole seismics to check the diameter of jet grouting columns - Improving the parallel seismic methods for precise length measurement of piles and foundation walls  Seismic migration methods to improve ultrasonic imaging of foundation slabs  Seismological tools to monitor subtle changes in concrete constructions The author strongly believes that the cooperation between geophysics and civil engineering, which is obviously becoming stronger and stronger, will lead to a large number of innovative approaches for investigations tasks currently stillModern geophysical methods might be either directly applied to foundations or integrated into existing testing schemes to assist in quality assurance and inspections.

A lot of challenges and chances for science and technology are right here.zeige mehrzeige weniger
