THE USE OF SMART SENSORS FOR TESTS OF LOADED CONCRETE PILES
Carlos Santos, Carlos Oliveira Costa, Helena G. Ramos · 2001
A lot of geotechnical engineering problems can be analysed in situ with tests of horizontal and vertical loaded piles. These are required, for instance, to study the behaviour of piles isolated and in groups. Based on the emergent concept of smart sensor a unit was developed that converts the deformation of the concrete pile measured by an LVDT on digital information. This unit is integrated on a local area network supervised by a command unit located at the surface. The communication protocol is based on a master-slave structure supported by dedicated developed commands.
