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...
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...
Ports '86
Ports '86 had the theme of Innovations in Port Engineering and Development with keynote speakers looking ahead to Port Development in the 1990's. The program...
Taming Lively Buildings
Mechanical damping systems are increasingly being used for controlling dynamic responses of tall buildings. Several types of dampers are described, and compared, beginning with the three...
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,...
