Poison Oak, Mistakes, and Lessons
When things go wrong in geotechnicalengineering ? like ground movements andearthwork construction delays ? failureinvestigations are often performed. In a typical geotechnical project, the path is relatively...
Heave Compensated Landing System - A Novel Tool for Subsea Intervention
This paper presents a new intervention system that allows the use of a low cost workboat to deploy and recover delicate payloads in subsea installations. Vessel motions are decoupled from the subsea package...
Ground Feature Monitoring Using Satellite Imagery: How Interferometric Stacking of SAR Can Mitigate Geo-Disasters Along Transportation Corridors
Landslides, debris flows, and other types of ground movements are among the most common hazards to humans and infrastructure. According to the United States Geological Survey, annual domestic...
Power Shift
Engineers designing a Manhattan skyscraper with offices in the lower floors and residences in the upper found that they had to employ several unusual methods to accommodate client needs....
Design of Isolated Structures
This chapter examines the design of isolated structures. Topics include governing design codes; design of isolated buildings; design of isolated bridges and viaducts; and issues related...
Frozen Ground Engineering
This new edition gives a peerless presentation of soil mechanics for frozen ground conditions and a variety of frozen ground support systems used on construction project worldwide. An...
Design and Construction of the Pier J Breakwaters at the Port of Long Beach, California
Several different alternatives to mitigate surge activity were investigated. The most acceptable solution was a pair of new breakwaters that altered the basin geometry to change the basin...
Saving Saluda
One of the largest roller-compacted-concrete berms in the United States will stand sentinel in case South Carolina's Saluda Dam undergoes liquifaction in response to strong...
New Parameters to Model Ground Motions
The paper presents three new parameters to characterize earthquake-induced ground motions. All three parameters evolve from the concept of response spectra, and are termed 3D response...
Fragility Curves and Seismic Loss Estimation Methodologies Based on Insurance Data
Loss data for single family dwellings from the 1994 Northridge, California, earthquake were correlated with ground motion with the aim of determining ground motion-based fragility curves....
Towers in Motion (available in Structural Engineering Special Section only)
Undersea towers are typically designed to rigidly resist the forces of water and wind. But one type of tower is designed to be flexible and, rather than rely on its platform strength to...
Losing Ground
Unusual engineering approaches, careful studies of earth and water movements, and a multi-organizational project team that worked cooperatively lead to the successful replacement of the...
Geotechnical Earthquake Engineering and Soil Dynamics III
This proceedings,
Compensation Grouting
To minimize ground movement while tunneling a sewer 5 m below Toronto's Spadina subway line, engineers used special instrumentation, tunneling control and grouting to limit...
An Analysis of Characteristics of Basset Force on Particles Accelerating in Arbitrary Flow Field
In present study of solid-liquid two phase flow, the effect of Basset force on a particle moving unsteadily in a non-uniform flow is not very clear. For this reason, the properties of...
A Comparative Study of the Transformed Methods for Solving Richards' Equation
The Richards' equation represents the movement of water in both saturated and unsaturated porous medium. The numerical solution to this equation is difficult because the algebraic...
Channel Junction Effects in Channel Network Flow Simulation
In this paper, the momentum equations, which are applicable at channel junctions, are suggested based on the conservation of momentum flux. In the equation, the lateral inflow angles are...
Earthquake Design and Performance of Solid Waste Landfills
This proceedings contains invited and contributed papers for the technical session on
Strong-Motion Data Processing
Processing of strong-motion earthquake accelerograms is now carried out routinely on a world-wide basis. Two international workshops have given participants the opportunity to assess their...
Real-time Motion Vision for Robot Control in Unstructured Environments
The control of robots in unstructured environments demands real-time, general purpose vision. We have designed a visual tracking system which makes use of motion to pick out and track...
