Abstract Studies in recent decades demonstrate the significant effect of stress configuration (e.g., vertical and lateral confinement) on shear strength or, this study, cone penetration test (CPT) results. Addition a surcharge over ground changes condition, consequently, CPT tip resistance. In results different CPTs conducted before after backfilling with various thicknesses land development pr...

Cone penetration testing (CPT) is a preferred method for characterizing soil profiles evaluating seismic liquefaction triggering potential. However, CPT has limitations in highly stratified because the measured tip resistance (qc) of cone penetrometer influenced by properties soils above and below tip. This results qc values that appear “blurred” at sediment layer boundaries, inhibiting our abi...

Experimental assessment of the reverse algorithms that enable the extraction of plastic properties from the load–depth of penetration curves was conducted. Results show that they predict the stresses at 3.3% and 5.7% representative strains for Berkovich and 60 cone-equivalent three-sided pyramidal indenters, respectively, with good accuracy. It was shown that the uniaxial stress–strain curves c...

Soil shear strength is an important indicator of soil erosion sensitivity and the tillage performance cultivated layer. Measuring at a field scale difficult, time-consuming, costly. This study proposes new method to predict parameters (cohesion internal friction angle) by combining cone penetration test (CPT) data properties. A portable CPT measuring device with two pressure sensors was designe...

Cone penetration testing (CPT) is one of the most efficient and versatile methods currently available for geotechnical, lithostratigraphic and hydrogeological site characterization. Currently available methods for soil behaviour type classification (SBT) of CPT data however have severe limitations, often restricting their application to a local scale. For parameterization of regional groundwate...

The Newcastle Dilatometer (NDMT) developed by Akbar in 2001 has a distinctive feature that it loads the soil with a rigid piston in place of flexible membrane as in the Marchetti Dilatometer (MDMT). Based on the previous research works carried out using the NDMT in normally consolidated soils, it has been found that the material and dilatometer indices from the NDMT data can be used to classify...

Several processes allow the improvement of soils such as vibrocompaction, stony columns, static horizontal compaction etc. These reduce risk liquefaction potential and making it possible to build on this type soil when space restriction require it. Stone columns are a recognized method improvement, which consists creating large diameter using special vibrators with granular filling materials in...

The Cone Penetration Test (CPT) is a common in-situ test which generally investigates a much greater volume of soil more quickly than possible from sampling and laboratory tests. Therefore, it has the potential to realize both cost savings and assessment of soil properties rapidly and continuously. The principle objective of this paper is to demonstrate the feasibility and efficiency of using a...
