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...
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...
Modeling the Movement of Volatile Organic Chemicals with Unsaturated Flow
Over the past decade, the rate of groundwater contamination by volatile organic chemicals (VOCs) has increased. Therefore, for both groundwater protection and cleanup, it is necessary...
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...
Coupling Free Vortex Energy Dissipation with Sediment Control
The paper reports on studies showing that sediment control down to the abrasive limit of 30 micron sand and energy dissipation can be achieved simultaneously with a Teacup free vortex...
Reservoir Sedimentation and Desilting in Taiwan
The island of Taiwan is infested with numerous flashy streams with steep slopes and huge sediment loads, thus, the major reservoirs have experienced heavy sediment deposit. The encroachment...
Air-Water Oxygen Transfer at Spillways and Hydraulic Jumps
Dissolved oxygen measurements are reported for seven spillway structures in the vicinity of Minneapolis, Minnesota, corresponding to 27 individual surveys. The surveys are taken during...
Management Practices for Erosion and Sediment Control in Irrigated Agriculture
Basin irrigating rice can reduce suspended sediment loads in water because the basins serve as sediment retention basins. Furrow erosion causes significant suspended sediment loads in...
The Effect of Storms on Pollution Loading Estimates
A rather extensive field and modeling program is underway in the Sandusky Bay/Nearshore region of Lake Erie and the objective of this paper is to summarize the preliminary results of a...
