Listening for deterioration and failure: Towards smart geotechnical infrastructure
Global change is accelerating the rate of deterioration of geotechnical infrastructure systems.
There is an urgent need for monitoring strategies that can be used to assess existing, ageing
infrastructure through retrofitting sensors at discrete locations to detect and provide early warning
of limit state failures. This paper describes a novel approach for smart geotechnical infrastructure
that ‘listens’ to acoustic emission (AE) generated by geotechnical asset deterioration and failure.
AE rates generated by geotechnical systems have been proven to be proportional to deformation
rates. AE is becoming an accepted monitoring technology for geotechnical applications; however,
challenges still exist to develop widely applicable AE interpretation strategies. This paper places
AE geotechnical monitoring in a smart infrastructure context and presents: the key factors
influencing AE propagation and attenuation in buried structural elements; techniques for
quantifying AE parameters; and AE interpretation frameworks for extracting information and
knowledge on the deformation and strength behaviour of geotechnical infrastructure systems. AE
interpretation strategies for exemplar applications (e.g. slopes, pile foundations and buried
pipelines) are developed and demonstrated through element- and large-scale experiments and
field trials.
