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...
Initial Results From an In-Situ Consolidometer
An In-Situ Consolidation Evaluation Device (ICED) was developed for field measurement of consolidation parameters by electro-osmosis. A brief description of the test apparatus and the...
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...
North American Standard Penetration Test Practice: An Essay
The Standard Penetration Test (SPT) is the in situ mechanical soil test most used by North American geotechnical practitioners. The equipment and procedures of the test have periodically...
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)...
Lateral Stress Measurement During Cone Penetration
A lateral stress sensing cone penetrometer (LSSCP) was designed and fabricated. Based on the results of calibration chamber tests in sand, relationships between measured lateral stress,...
The Pressuremeter for Foundations: French Experience
The paper presents historical information on the development of the pressuremeter and its application in the Laboratories Central des Ponts el Chaussees (LCPC). The continuous research...
Designing for Maintainability
Inspection and maintenance guidelines are unavailable for many buildings. Building owners seldom have the benefit of such information because buildings are often considered passive systems,...
Parking Lot Gets White Top
The many-acre parking lot at the Valley Fair Mall shopping center in Salt Lake City, Utah is described. In 1985 the asphalt pavement was overlaid with concrete, making it one of the relatively...
Construction by Computer
Olympia & York, the developers of the 8 million sq ft World Financial Center in lower Manhattan are using a computerized scheduling system to keep the flow of materials into the...
Development of Data Quality Indicators for Indoor Air Pollution Measurements
Indoor air quality measurements pose a unique problem for the application of traditional Quality Assurance/Quality Control approaches. The lack of reference methods and materials in some...
Testing of Permeable Materials for Retaining Contaminants in Subsurface Leachates
The use of a permeable, retentive treatment system could remove both organic and inorganic contaminants while still allowing flow. A testing procedure for determining the amounts of priority...
Decreasing Clay's Permeability Using Aluminum Salts
The permeabilities of montmorillonite and kaolinite clays were reduced by precipitating aluminum hydroxide in the pores of the clay. The precipitate was formed by permeating the clays...
