Cone penetration testing in polar snow
Innovative Cone Penetration Testing (CPT) using adapted commercial CPT equipment was conducted in Antarctica in early 2010 in an attempt to assess the strength of polar snow; additionally, application of CPT data was considered, particularly in estimating surface bearing capacity. Almost 100 CPT …

Scaling effect in cone penetration testing in sand
The Cone Penetration Test (CPT) was developed originally in Holland in the 1930’s as a device which provides a small scale model of a pile foundation. Early versions were simple cone points for which the only measurement was the thrust required to push the point through the ground. Over the past 20 …

Cone Penetration Testing and Hydrogeological Monitoring of a Retrogressive Landslide in Champlain Sea Clay
… susceptible to large retrogressive landslides. A cone penetration testing and hydrogeological program was developed in this thesis to characterize a retrogressive landslide along a creek valley consisting mainly of Champlain Sea Clay. As Champlain Sea Clay has been commonly shown to consist of …

Location Of Sinkhole Confining Breach Using Groundwater Flow Patterns Derived From Cone Penetration Testing
… sinkholes 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 …

Use of Cone Penetration Testing in the Interpretation of Ground Shaking From Paleoliquefaction Evidence
To evaluate seismic hazard in regions of infrequent earthquakes it is often necessary to rely on evidence left from earthquakes that occurred before seismographs were available. This evidence can consist of human observations or of evidence left in the geologic record. The New Madrid Seismic Zone …

Measuring Liquefied Residual Strength Using Full-Scale Shake Table Cyclic Simple Shear Tests
… strength of #2/16 Monterey Sand. A simple shear testing apparatus was mounted to a full-scale one-dimensional shake table to mimic a confined layer of saturated sand subjected to strong ground motions. Testing was performed at the Parson’s Geotechnical and Earthquake Laboratory at California …

Investigation of Pore Pressures During High-Velocity Impact by a Free Fall Penetrometer
… measurements are extensively used in traditional cone penetration testing, but their usage and interpretation is still limited for FFP testing. This thesis represents an effort to advance the interpretation of pore pressure measurements from FFP testing. Data was collected using the torpedo-shaped …

REAL TIME MONITORING OF VOLUMETRIC WATER CONTENT IN RECLAIMED MINE WASTE USING CONE PENETRATION - TIME DOMAIN REFLECTOMETRY
… component added to conventional geotechnical cone penetration testing (CPT). Time domain reflectometry measures the volumetric water content of a soil by characterizing the dielectric constant of the soil – a property that is strongly dependant on volumetric water content. The sensor design is …

Quaternary geology of the German North Sea and Western Irish Sea Mud Belt: revised stratigraphies, geotechnical properties, sedimentology and anthropogenic impacts
… a combination of core, seismic and in-situ Cone Penetration Testing (CPT) data was used to identify sedimentary units, place them within a morphological context, relate them to glacial or interglacial periods stratigraphically, and correlate them across the German North Sea. Subsequently, we …

LITHOLOGIC AND HYDROGEOLOGIC CONTROLS ON THE OCCURRENCE, TRANSPORT, AND FATE OF MTBE IN FINE GRAINED GLACIAL-LACUSTRINE SEDIMENTS
… sampling, geotechnical tools including cone penetration testing (CPT) and Membrane Interface Probe (MIP), were used to examine subtle changes in sand, silt and clay. These tests were supported by site coring, grain size analyses, and lab and field hydraulic conductivity testing. CPT …

Full-Scale Shake Table Cyclic Simple Shear Testing of Liquefiable Soil
… previously observed, or in tabletop laboratory testing. The study detailed herein is a controlled laboratory test performed at full scale to allow for the measurement of field-scale index testing before and after cyclic loading. Testing was performed at the Parson’s geotechnical and Earthquake …

Development of the Spectral-Analysis-of-Body-Waves (SABW) method for downhole seismic testing with boreholes or penetrometers
Downhole seismic testing and seismic cone penetration testing (SCPT) have shown little change since the 1990’s, with essentially the same sensors, sources, test procedures and analytical methods being used. In these tests, the time differences of first-arrivals or other reference points early in …

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 …

A Regional Study on Champlain Sea Clay: Empirical Prediction of Consolidation Parameters and Statistical Characterization of Undrained Shear Strength Based on Historical Geotechnical Data
… consolidation tests performed in the laboratory testing using high-quality undisturbed soil samples. Undrained shear strength, S_u, of clay is one of the key parameters required in the ultimate limit state (ULS) design of geotechnical structures for short-term stability analyses, which can be …
