In-Situ Testing with the Flat Dilatometer (DMT) for Geotechnical Applications (Numac Webinar #8)

Numac webinar #8 - July 2022 'In-Situ Testing with the Flat Dilatometer (DMT) for Geotechnical Applications'
Presented by: Eng. Diego Marchetti (Director at Studio Prof. Marchetti).

Marchetti’s Flat Dilatometer Test (DMT) consists of a steel membrane that is pneumatically expanded against the soil at 0.2-m intervals. During this process, pressure readings are recorded and used to obtain information on soil stiffness and stress history.

The blade shaped probe makes DMT particularly sensitive to horizontal stress and causes less distortion than conical probes.

Aimed to geotechnical and tailings engineers, this technical webinar explored the capabilities of DMT systems and discussed aspects that are paramount for the effective design of DMT investigations and the adequate interpretation of DMT data.
