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...

Residual Soil Settlement From Pressuremeter Moduli
The Menard pressuremeter test is briefly described, and practical drilling techniques are summarized for Piedmont residual soils. Applications and limitations of the pressuremeter are...

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...

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...

Dilatometer Tests in Sand
The paper presents two applications of the dilatometer test in sands: control of compaction and determination of constrained modulus. Twelve dilatometer tests were carried out before and...

Laboratory and Field Evaluation of Cone Penetrometers
Cone penetrometers from 8 organizations have been studied by performing laboratory tests and field tests. The testing show that pore pressure and temperature zero shift affect significantly...

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...

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...

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...

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....

Interpretation of CPT Data for Design of Earth Dams Near Tehachapi, California
The Static Cone Penetration Test (CPT) was used to obtain needed geotechnical information for design and construction of two small earth dams near Tehachapi, California. The basic CPT...

The Use of Cone Penetrometer Testing to Investigate Sand Fill Subsidence Beneath Highways
During construction of Interstate I-10 between Baton Rouge and LaPlace, Louisiana, highly organic swamp deposits were excavated and replaced with hydraulically pumped river sand. The main...

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...

Comparison Between In-Situ Test Results
Penetration tests provide a means of obtaining data from which estimations can be made of the bearing capacity, settlement and liquefaction potential of the soils tested. Empirical formulae...

Implications of Soluble Microbial Products (SMP) Formation on Biofilm Reactor Performance
The objective of this study is to evaluate the implications of SMP formation for biofilm treatment. To do so, the extended steady-state model was applied to predict effluent concentrations...

The Optimization of Nitrification and Denitrification in Plug-Flow Activated Sludge Systems Treating Municipal Wastestreams
Most conventional plug-flow activated sludge plants experience nitrification, particularly during higher temperature conditions. Under these circumstances, additional power is required...

Recyclying of Dust from Electric Arc Funances�An Experimental Evaluation
Each year the electric arc steelmaking industry generates approximately 650,000 tons of dusts containing valuable metallic resources such as iron, zinc, lead, and chromium. EAF dust is...

Design Considerations and Experiences with VOC Treatment Technologies
This paper presents a review of design considerations and experiences with packed column aeration for removal of volatile organic chemicals (VOC) from groundwater at various locations...

Emission and Control of Volatile Organics in Hazardous Waste Landfills
Landfill simulation and modeling can provide a useful tool in the management of hazardous wastes to estimate the vapor phase emissions of pollutants so that a realistic assessment can...

Permeability of Grouts Subjected to Chemicals
This paper presents the more recent results of a testing program which evaluated the long-term resistance to percolation of grouted soils, using acrylate, urethane and cement-bentonite...
