Nondestructive Testing involves the use of methods such as wave
propagation, electromagnetism, electrical conductivity, and thermal
conductivity to test structural integrity and thereby allow
nondestructive assessment of structures and the possibility of
structural failures before they occur.
Nondestructive Testing of Deep Foundations covers
different techniques designed to provide information about the
integrity and quality of the material that makes up a deep
foundation.
Nondestructive Testing methods are used at all stages of a
structure's life - from new construction quality control to
residual lifetime prediction, and even during the monitoring of
demolition. In addition, Nondestructive Testing is being
increasingly specified in deep foundation projects, though often
without a good understanding of its limitations and with the result
that methods are often misused. In order to be able to specify an
appropriate method, or to recognize an inappropriate specification,
it is necessary for the engineer, specifier and/or contractor to
understand the capabilities and limitations of each of the methods
currently in use.
Nondestructive Testing of Deep
Foundations:
* Describes the most commonly used deep foundation construction
techniques, including typical use of material
* Provides a brief history of the development of commercially
available nondestructive methods
* Summarises each method's capabilities and limitations
* Acts as a one stop reference drawing together resources only
previously available in conference proceedings and journal
papers
This manual will prove to be a welcome addition to the bookshelf
of all practitioners in civil/structural and geotechnical
engineering and architecture. It will also provide a valuable
insight into this highly technical field for university
researchers, lecturers and postgraduate students in
civil/structural and geotechnical engineering.
