Strength of Fine-Grained Soils Using the Piezocone
Evaluation has been made of several theories and methods for deducing the undrained and effective stress strength of saturated fine-grained soil from piezocone test results. Bearing capacity...
Pore Pressure Effects in Borehole Shear Testing
The effects of excess pore pressures on shear strength results obtained using the Borehole Shear Test (BST) were investigated. Pore pressures were measured during the consolidation, shear,...
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...
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....
Vane Shear Testing for Staged Construction
Staged construction was used for the earthfill embankment of Birch Dam in order to compensate for low strength clays in the foundation. Sampling and testing of foundation soils verified...
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...
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....
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...
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...
Tunnel Ceiling Replaced over traffic
The ceiling of the Holland Tunnel under the Hudson River, connecting New Jersey and Manhattan, was 59 years old and needed replacement, a big job because there are 3 miles of ceiling in...
Postmodern Engineering
Momentum Place is a postmodern skyscraper in Dallas designed by architects John Burgee and Philip Johnson. The Datum-Moore Partnership, structural engineers, designed the structural system...
Recyclying of Dust from Electric Arc Funances�An Experimental Evaluation
Each year the electric arc steelmaking industry generates approximately 650,000 tons of dusts containing valuable metallic resources such as iron, zinc, lead, and chromium. EAF dust is...
Risk-Based Design of Inspection Programs for Detecting Leaky Underground Storage Tanks
A mathematical framework is developed for estimating the effectiveness of large-scale inspection programs for leaky underground storage tanks. The framework incorporates the leak likelihood...
Relative Landslide Susceptibility in Davis County, Utah?A Multivariate Approach
The complex distribution of soil properties makes prediction of slope stability extremely difficult in these mountain watersheds. The need to assess these watersheds for their susceptibility...
Erosion and Sedimentation Processes in Irrigation
Soil erosion occurs when fluid in motion detaches and transports soil particles. Sedimentation occurs when the fluid transport capacity decreases. Both the hydraulic forces of moving water...
Effect of Baghdad City Sewage Treatment Effluents on Dissolved Oxygen Profiles of an Iraqi River
The paper presents measured dissolved oxygen (DO) profiles in an Iraqi river in the vicinity of Baghdad City. The effect of the effluent discharges from Baghdad Sewage Treatment Plant...
Response of the Citanduy River to Developments
The sinuous alluvial reach of the Citanduy River in Java, Indonesia has been surprisingly stable in spite of man-made cutoffs which have reduced the channel length from 98. 7 km to 78....
Implications of Nitrogen Transport by the Okanagan River
The long-term mean of total nitrogen load estimated in the river channel above the inlet to Skaha Lake is 906 lb day** minus **1. The apportionment of ammonia and nitrate plus nitrite...
Rehabbing under Traffic
Redecking the Golden Gate Bridge with a light weight orthotropic steel plate deck left the 49 year old monument 11,000 tons lighter, 2 feet wider, and ready to carry traffic for the next...
Top Projects of 1986
In the 1986 ASCE competition to select the Outstanding Civil Engineering Achievement of the Year, 14 projects were nominated. This article describes the 10 non-winners. Technically the...
