Probabilistic Study of SPT Liquefaction Analysis
The influence of earthquake magnitude upon the commonly used correlation between Standard Penetration Test (SPT) blow count and liquefaction potential is evaluated using a probabilistic...
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 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...
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...
Bearing Capacity of Footings on Clay CPT Method
A method is proposed to predict the ultimate bearing pressure for footings on clay using data from cone penetration tests. This method relates the ratio of ultimate soil bearing for a...
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...
Analysis of Liquefaction Potential by Insitu Testing
This paper describes the results of insitu testing performed to assess the liquefaction potential of a sand formation at a site for a proposed large industrial facility in East Central...
Effctive Stress Interpretation of In-situ Tests
Significant differences in terms of load-settlement curves obtained from Plate Load Tests (PLT) and q//c profiles obtained from Static Cone Penetration Tests (SCPT) at two sites with different...
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...
Use of Piezometer Cone Data
The piezometer cone is generally regarded as the most efficient tool for stratigraphic logging of soft soils. A thin pore pressure element (5 mm thick) can sense layers a few centimeters...
CPT Indexing of In Situ OCR in Clays
Cone penetration tests may be used to index the in situ preconsolidation pressure in clay deposits. A specified relationship between C//u/ sigma //vo and the overconsolidation ratio (OCR)...
Audits & Analyses?New Jersey's Approach
The New Jersey Department of Environmental Protection is responsible for implementing environmental policy and administering a regulatory structure based on reliable research and monitoring....
Computer Modeling of Collection Systems for Sulfide Evaluation (
An overview of two computer models and a nomograph model for sulfide prediction is presented. The first program, 'SULF. BAS', is a Basic Language computer model...
Sulfide Corrosion and Control in the City of Modesto Primary Effluent Outfall (
The City of Modesto has a 60 inch diameter, 6- one-half mile long reinforced concrete pipeline conveying primary effluent from the primary treatment plant to the remote oxidation pond...
Assessment of Analytical Techniques for Monitoring Petroleum Waste Land Treatment Systems
Optimization of wastewater land treatment effectiveness requires current knowledge of the microbiological ecosystem. Environmental parameters must be measured if they are to be adjusted...
Studies of Long-Term Water Losses
The water-loss time series are formulated for the studied watersheds in the Ohio River Basin through the use of the law of water balance to the system inputs and corresponding outputs....
Deferred Drainage?Prudent Policy or Tactical Folly?
The practice of deferring drains has not always worked out as planned. This is particularly true of large outlet drains such as the San Luis Drain in the Central Valley of California and...
An Integrated Conceptual Expert System for Flood and Water Pollution Management
One particularly practical role for an expert system (ES) is as an interface between a complex computer model and an inexperienced user or novice. The software is applied to the USEPA...
Intelligent Central Database System for Synchronized Distributed Processing of Large Hydrologic Packages in Local Area Networks
The nodes of a local area network can be dedicated to the independent routines of a large hydrologic/hydraulic package. The server of the network can be dedicated to the control of the...
