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...
The DMT - ?hc Method for Piles Driven in Clay
This paper presents a tentative method for evaluating the limiting skin friction f//s for piles driven in clay based on sigma //h'c (horizontal effective stress at the interface...
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...
Measurement of Vertical Ground Vibrations
This paper examines the use of surface and embedded mountings, to which transducers are attached for the measurement of free field vertical ground vibrations. Upper limits to the frequency...
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...
Soil Improvement Evaluation by CPT for Tanks
Trial soil improvement by gravel compaction piles and dynamic consolidation, and a subsequent full-scale loading test on loose volcanic ash soil were conducted prior to the design of large...
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...
Design Parameters for Grouted Piles in Rock From In-Situ Load Tests
A series of pile load tests were performed at an onshore site to develop final geotechnical parameters for the Gaviota platform foundation which consists of large diameter drilled and...
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...
Skin Friction Evaluated From Friction Meter Test
This paper first describes the features of a specially developed friction meter and its operation method, and then reports in-situ test results conducted on various types of soils at two...
Uplist Capacity of Pile Foundations Using CPT Data
Southern California Edison Company has performed field uplift load tests on concrete driven piles, cast-in-place straight shaft piles and cast-in-place belled piers along transmission...
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...
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....
N-Values Used to Predict Settlements of Piles in Egypt
A method is proposed for using the standard penetration N-values to predict the load-settlement curves for different piles used in Egyptian soils. The method is based on H. G. Poulos-E....
Cable Stays Catch On
The three completed cable stayed bridges in the U.S.�Pasco-Kennewick in Washington, Luling-Destrehan in Louisiana and East Huntington in West Virginia�will soon be joined by another half...
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,...
Effect of Particle Size on Sludge Dewaterability
Using a modified Buchner funnel apparatus to measure specific resistance and a sequential centrifugation/filtration procedure to fractionate a sludge, it was possible to more precisely...
Issues in Specifying Climate Forcing of Variability
Several issues arise in the specification of the role of climatic forcing of variability of water resources. The effects of human intervention must be removed so that the climate signal...
Seawater Intrusion in Salinas Valley, California
The rate of intrusion has been estimated to be about 19,000 acre-feet per year. If no action is taken to halt the intrusion, it is projected that in the year 2000 there will be as much...
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...
