Soil Classification from Piezocone Penetration Test Using Fuzzy Clustering and Neuro-Fuzzy Theory

Applied Sciences, 2022
The advantage of the piezocone penetration test is a guarantee of continuous data, which are a source of reliable interpretation of the target soil layer. Much research has been carried out for several decades, and several classification charts have been

Cone penetration index for soil behaviour type prediction [PDF]

Scientific Reports, 2022
Several approaches have been proposed to classify soil types using both cone and piezocone penetration tests. The chart relating the normalized cone resistance (Q tn ) and the friction ratio (F r ) has proven to be the most reliable method.

Estimating Hydraulic Conductivity of Overconsolidated Soils Based on Piezocone Penetration Test (PCPT) [PDF]

Infrastructures, 2021
Overconsolidated (OC) soils may develop a low or negative pore pressure during PCPT. Thus, it is challenging to develop an “on-the-fly” estimation of hydraulic conductivity from PCPT results.

Effect of penetration rate and filter location on piezocone test results

KSCE Journal of Civil Engineering, 2004
The effects of penetration rate on the piezocone penetration and dissipation test results with filter element locations were experimentally studied. Six kinds of piezocone tests were conducted for the U1 (filter element at the cone tip) and U2 (filter element behind the cone base) miniature piezocone penetrometers and the K33 specimen (mixture of 33 ...

Improving the interpretation of undrained shear strength from piezocone penetration tests by integrating soil physical properties using a hybrid meta-heuristic algorithm

Journal of Rock Mechanics and Geotechnical Engineering
Conventional empirical equations for estimating undrained shear strength (su) from piezocone penetration test (CPTu) data, without incorporating soil physical properties, often lack the accuracy and robustness required for geotechnical site ...

Site observations of weathered granitic soils subjected to cementation and partial drainage using SCPTU

Journal of Rock Mechanics and Geotechnical Engineering, 2023
Because of the cementation inherited from the parent rock, weathered granitic soil is usually susceptible to disturbance, which poses considerable challenges for laboratory characterization.
