Energy transfer and grain size effects during the Standard Penetration Test (SPT) and Large Penetration Test (LPT)
The Standard Penetration Test (SPT) is the most widely used in-situ soil test in the world. "Large Penetration Test" (LPT) is a term used to describe any scaled up version of the SPT. Several types of LPT have been developed around the world for the purpose of characterizing gravel deposits, as SPT …

Standard penetration test correlations for Las Vegas soils
Standard penetration tests (SPT) are used to approximate soil properties including the consistency, cohesion and the internal angle of friction. Due to the frequency of cemented sands, gravel and clay in the Las Vegas Valley, the generally accepted SPT correlations vary from actual local …

Interpretation of cone penetration test data for underconsolidated clay
In this study, cone penetration test data is correlated to vane shear and triaxial undrained shear strength test data for a saturated and underconsolidated marine clay. It is shown that cone penetration test data not corrected for pore pressures underestimates undrained shear strength. …

Dynamic analysis of dynamic cone penetration test for subgrade compaction assessment
… weight obtained from a laboratory compaction test. Most DOTs typically require that the in-place dry unit weight for compacted soil be over 95% of the laboratory maximum dry unit weight obtained from Standard Proctor compaction test results. Nuclear gauges may be used to determine the in-place …

Evaluation of liquefaction potential of silty sand based on Cone Penetration Test
… a rational basis for the use of the Cone Penetration Test (CPT) to predict Iiquefaction resistance in these materials. The study is primarily experimental, relying on laboratory and field testing and the use of a unique, large scale calibration chamber. The calibration chamber allows the …

Numerical simulation and field verification of inclined piezocone penetration test in cohesive soils
… of soil anisotropy on the inclined piezocone penetration test in normally consolidated cohesive soils. The piezocone penetration is numerically simulated using the commercial finite element code ABAQUS. The saturated clay is modeled as a two-phase material and the effective stress principle is …

Influence of penetration force in clay soils due to speed rate effect
This research discusses the effects of penetration rate on the penetration resistance in clayey soils for five different speeds of penetrations. In order to install the pile through hydraulic system, it is crucial to understand the required penetration force needed to do the job. Generally, the …

Load and resistance factor design of drilled shafts in shale using SPT and TCP measurements
… notoriously difficult to effectively sample and test, which poses practical problems for those tasked with designing drilled shafts in such materials. The difficulty in sampling shale has lead geotechnical engineers to consider in-situ tests, such as the Standard Penetration Test (SPT) and the …

Location Of Sinkhole Confining Breach Using Groundwater Flow Patterns Derived From Cone Penetration Testing
… that have occurred in the area. Use of Cone Penetration Test (CPT) soundings, in conjunction with conventional soil borings are becoming more common in the assessment of subsurface soil conditions in the vicinity of sinkhole-related ground surface. The penetration resistance data by CPT can …

The Effects of Vibration on the Penetration Resistance and Pore Water Pressure in Sands
The current approach for using cone penetration test data to estimate soil behavior during seismic loading involves the comparison of the seismic stresses imparted into a soil mass during an earthquake to the penetration resistance measured during an in-situ test. The approach involves an indirect …

Movements of footings and retaining walls
… Eleven of the methods are based on Standard Penetration Test Results, while Schmertmann’s method is based on Cone Penetration Test Results. The study showed that methods which are more accurate tend to underestimate settlements about half of the time; while those which are more reliable (in …

Efeito do tempo de carregamento e a questão dos recalques de estacas em provas de carga
… pile performance when subjected to vertical load tests. The most usual types of piles are investigated. Load tests are analysed with the purpose of verifying the influence of the loading rate on settlements and on failure loads. It is observed that a more rapid loading - or less rigorous …

Estudo de correlações entre os ensaios de penetração estática e dinâmica e suas aplicações ao projeto de fundações profundas
The ever present interest in applying field tests to determine the bearing capacity of foundations, particularly deep foundations, explains the necessity to check, or modify, existing correlations between the "standard penetration test" and the "diepsondering". Considerations are made concerning …

Review of CPT based design methods for estimating axial capacity of driven piles in siliceous sand
The Cone Penetration Test has been used for more than 30 years for soil exploration purposes. Its similarities in mode of installation with driven piles provides the potential of linking key variables of pile design and performance, such as base resistance and shaft friction, to measured cone tip …
