Cone penetration test

Description:This data helps determine the shear modulus and Poisson's ratio at intervals through the soil column for soil liquefaction analysis and low-strain soil strength analysis. Pore water pressure data aids determining stratigraphy and is primarily used to correct tip friction values for those effects. Over water, CPTs can be conducted from vessels, barges and jack-up platforms. Low impact — CPT provides a continuous subsurface picture with less ground disturbance than drilling Highly mobile — CPT can be used in most situations where ground investigation is required. Its increased accuracy, speed of deployment, more continuous soil profile and reduced cost over other soil testing methods. The filter is usually located either on the cone tip the so-called U1 position , immediately behind the cone tip the most common U2 position or behind the friction sleeve U3 position.
