Use of SPT and CPT Tests for Evaluating the Liquefaction Resistance of Sands
A cone penetration test (CPT)-liquefaction resistance relationship has been established using the large body of standard penetration test (SPT) data. Factors for relating CPT tip resistance...

In Situ Testing for Ground Modification Techniques
Presented are the status of three in situ testing techniques in relation to Ground Modification and a general overview of eight Ground Modification methods with case histories and appropriate...

Electrical In Situ Measurements for Predicting Behavior of Soils
A new method is presented for predicting the in situ stress-strain behavior of fine grained soils based upon in situ measurements of its electrical properties. The method involves the...

Comparison of the SPT,CPT, SV and Electrical Methods of Evaluating Earthquake Induced Liquefaction Susceptibility in Ying Kou City During the Haicheng Earthquake
The capability of SPT, CPT, Shear Wave Velocity and Electrical methods to evaluate earthquake induced liquefaction susceptibility of soil deposits consisting of sensitive clayey silts...

Predictions of Pile Shaft Capacity With the PLS Cell
In situ measurements of stresses and pore pressures on a model pile shaft, the Piezo-Lateral Stress (PLS) cell, are utilized to reconstruct the conditions of load tests involving two large...

Liquefaction Study of Coal Refuse by Nuclear Gauges
This paper presents a technique for utilizing nuclear gauges to determine density and moisture content continuously throughout refuse embankments and slurry reservoirs. The nuclear measurements...

A Modern Cone Penetration Testing Vehicle
The geotechnical group at the University of Florida recently purchased a new insitu testing cone truck. This is a powerful, all wheel drive, off-the-road vehicle designed specially for...

ECPT Investigation of a Slurry Trench Cutoff Wall
ECPT (electronic cone penetration testing) was used to investigate a soil-bentonite backfilled slurry trench cutoff wall at Calamus Dam in Nebraska, The wall was tested shortly after its...

Landslide Investigation Utilizing Electric Cone Penetration Testing
A geotechnical investigation was conducted of landsliding at a hillside residential property to evaluate both the extent of the landslide and the stability of the fill materials as well...

Waterfront Electric Cone Penetration Testing
Offshore deployment methods developed for use by the oil industry were combined with less expensive nearshore drill barge technology. This resulted in the successful completion of cone...

Cone Penetrometer Use on Uranium Mill Tailings
Piezocone data were found to be very reliable in the identification of uranium tailings according to the traditional categories of sands, sand-slime mixtures, and slimes by the use of...

In Situ Tests with K_o Stepped Blade
The results of field tests conducted using the K//o Stepped Blade to determine lateral stresses and other geotechnical properties are presented. The sites tested represent a wide range...

Electrical Method of Predicting In Situ Stress State of Normally Consolidated Clays
The electrical method was used to characterize the electrical anisotropy, shape and cementation of fine grained soils. It was found that for normally consolidated soils there is a strong...

Determining Sand Strength by Cone Penetrometer
Evaluation has been made of several theories and methods for deducing sand strength from cone resistance. Bearing capacity theories, cavity expansion theory, and empirical methods have...

Site Characterization Using the Cone Penetrometer Test
The Cone Penetrometer Test (CPT) when used in conjunction with a limited soil boring program can provide a more detailed and economical site characterization. This paper addresses how...

In-Situ Testing to Characterize Electric Transmission Line Routes
A review of the literature has shown few definitive studies which separate test variability from soil inhomogeneity. A sensitivity study was performed to evaluate the effects of the overall...

In Situ Testing of Calcareous Sand?Campos Basin
Sampling and in situ testing were used to investigate soil conditions for the installation of offshore platforms at the Campos Basin, Brazil. At these sites calcareous sand formations...

High Quality Sampling and In Situ Testing for Deep Water Geotechnical Site Investigation
This paper discusses methods that have been used to conduct geotechnical investigations in water depths up to 2500 feet. Investigations can be conducted from supply boats, geotechnical...

Effect of Cementation on the Cone Penetration Resistance of Sand
A laboratory study was conducted to investigate the effect of cementation on the cone penetration resistance of sand. A new apparatus to form homogeneous artificially cemented sand specimens...

In Situ Measurement of Permeability in Soft Clays
As part of an extensive field programme, the magnitude of errors due to clay remoulding and filter clogging in tests performed in common piezometers is evidenced. Comparisons between variable...
