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...

The Mudslide Profile Method to Measure the Undrained Shear Strength of Muds
Mudslides have been reported to have a very distinctive profile. Using this distinctive profile, a method is presented to analyze the stability of the mudslide at limit equilibrium conditions....

A Relationship Between Deformation Modulus and SPT N for Gravels
The results of over 200 horizontal plate load tests performed in situ in large diameter boreholes on gravels at various relative densities are used to develop a relationship between deformation...

Fast, Economical, Cone Testing of River Sediments
The objective of the study reported was to obtain quantitative geotechnical information over many square miles of Hudson River bottom. A hand held cone penetrometer was selected for use....

In-Place Permeability Measurement of Slurry Trench Cutoff Walls
A suggested procedure for the in-place measurement of slurry trench cutoff wall permeability is presented. The H. Bouwer and Rice method, employing a single observation well and variable-head...

In Situ Tests for Foundation Vibrations
There are several well established methods of determining shear modulus in situ and these are summarized in this paper. New techniques are being developed for in situ determination of...
