A Portable, Electrically-Driven Dutch Cone Penetrometer for Geotechnical Measurements in Soft Estuarine Sediments

We describe here a portable, electric penetrometer (PEP) for use in soft estuarine sediments. The PEP measures cone resistance, qC, and local unit side friction resistance, fS. It is composed of three components: the cone, the power drive system, and the data acquisition system. This instrument has a larger, more sensitive cone that can measure values of qC and fS in the range of 0-1.5 Kg/cm2. The cone is forced into the sediments by the power drive system and values of qC and fS are logged at 1-4 cm intervals by the data acquisition system. These data can then be used to calculate geotechnica... Mehr ...
