M.  aPortable CAT scanner applied to collapsible soil studies.  c1997  aThe soil collapse is causing huge losses to the grain producers of Mato Grosso State. As a result of this phenomenon many silos are showing signals of sinking. The soil collapse means a sudden reduction of soil volume, when submitted to a stress, due to a rise on its soil moisture. The collapse occurs when the soil is non-saturated and its structure is metastable. In this work, computerized tomography (CT) technique was applied to measure the reduction of voids caused by the soil collapse. The equipment used for these studies is a portable tomograph scanner developed at the Instrumentation Center of EMBRAPA/CNPDIA - Sao Carlos SP.  asoil  atomography  aSolo  aAgricultural instrumentation  aCollapse  aCongressos  aInstrumentacao agropecuaria  aPortable CAT scanner1 aCRUVINEL, P.
