Numerical Analysis of FFP Impact on Saturated Loose Sand
… numerical analysis was conducted by simulating calibration chamber FFP tests on saturated loose quartz sand. The numerical results using quasi-static properties resulted in a reaction of the sand softer than the actual calibration chamber test. This implied the necessity of considering HSR …

Development of Facilities for the Testing of Shear Stress Sensors
… and tested to progressively test the sensor: a calibration chamber to apply a mechanical shear stress under various temperatures and pressures, an impinging jet to test the sensor under an aerodynamic shear stress, and finally, a hypersonic wind tunnel in which the performance criteria will be …

Evaluation of liquefaction potential of silty sand based on Cone Penetration Test
… testing and the use of a unique, large scale calibration chamber. The calibration chamber allows the field environment to be duplicated in the laboratory where conditions can be closely controlled and accurately defined. One of the first problems to be overcome in the research was to determine …

Scaling effect in cone penetration testing in sand
… new, smaller cones in experimentation in modem calibration chambers with the knowledge that the test results are applicable for the cones that a.re more widely used in practice. The smaller cones offer several advantages in this type of work in that they facilitate the research considerably by …

Axial load transfer in large scale physical model drilled shaft foundations
… in a five-foot diameter by five-foot deep calibration chamber where soil conditions could be controlled. Soils tested were a loose clean sand, dense clean sand and compacted silty sand. A bladder system was used to apply vertical effective stress to the soil to simulate depths of embedment …

Experimental Study of the Displacements Caused by Cone Penetration in Sand
… testing facility, consisting of a half-circular calibration chamber with digital image correlation (DIC) capability, was developed for experimental simulation of cone penetration. The flat side of the chamber is transparent, made of Plexiglass. In individual tests, sand samples are prepared …

Numerical simulation and field verification of inclined piezocone penetration test in cohesive soils
… 1) As compared to the previously conducted calibration chamber tests, the finite element analysis results based on Anisotropic Modified Cam Clay Model (AMCCM) are overall in good agreement with the actual measurements. This indicates that the soil anisotropy plays an important role during …

Improving CPT-Based Earthquake Liquefaction Hazard Assessment at Challenging Soil Sites
… the numerical analyses and the laboratory CPT calibration chamber tests used to calibrate the numerical analyses is also proposed. Finally, a database of laboratory and numerically-generated CPT data is presented. It is shown how this database can be used to improve existing, and develop new, …

The Effects of Vibration on the Penetration Resistance and Pore Water Pressure in Sands
… Cone penetration tests were performed in a large calibration chamber in saturated sand samples prepared at different densities and stress levels. A total of 118 tests were performed as part of the study. The piezocone penetrometer used in the investigation was subjected to a vibratory load during …

Pore-water pressure accumulation under dynamic loadings
… but most correlations are based on limited calibration testing and/or require soil constitutive parameters from laboratory shear tests. The new framework is based on a limit pressure calculated using cavity expansion theory and a semi closed-form solution that is scaled to existing …
