Nonlinear Three Dimensional Analysis of Downdrag on Pile Groups
The downdrag on pile groups was investigated by using a numerical analysis and an analytical study. The emphasis was on quantifying the reduction of downdrag on piles in a group due to...
Settlement Prediction for Driven Piles and Pile Groups
Various methods of settlement prediction are reviewed for single piles and pile groups, and it is demonstrated that several of the methods give similar results. It is also found that the...
Settlement Analysis for 450 Meter Tall KLCC Towers
The site evaluation and settlement analysis performed for the two tallest buildings in the world currently under construction, are described. The site evaluation resulted in shifting building...
Vibration Induced Settlement From Blast Densification and Pile Driving
This paper describes settlement and vibration environments produced by two construction activities, blast densification and pile driving. Blasting is of interest because of the significant...
Movement of Foundations on Rock
This paper reviews methods for estimating the settlement of vertically loaded foundations on rock, with particular emphasis on shallow and piled foundations in and on soft rock....
Downdrag on Piles: Review and Recent Experimentation
A review of the literature on pile downdrag is provided, within the context of a recent full-scale study involving two pile groups driven in soft clay, subsequently surcharged by a 2.5...
Offshore Rescue
Restoration of wastewater ocean outfalls can be difficult, dangerous and environmentally challenging. Two recent projects, however, serve as examples of innovative outfall rehab. The first...
Bridge to the Future
The experimental Roize Bridge, near Grenoble, France, features an innovative composite space truss and unique modular construction methods for efficiency and economy. The Roize Bridge...
Fast Foundation for Soft Clay
This article describes the detailed foundation work and high-capacity piling design for a flue gas desulfurization (FGD) retrofit system for the Lambton Generation Station in Ontario,...
Input for Seismic Design of Major Structures
Effective seismic input considering the soil-structure interaction or soil-pile-structure interaction is presented. This approach takes the seismic wave as primitive input and considers...
Tension Pile Test
The California Department of Transportation is conducting FULL SCALE AXIAL LOAD TESTS of 34 piles. This research project/proof test is being jointly conducted by public agencies (Caltrans...
Predicting Turbine-Generator Foundation Vibrations
Two of the major considerations in the design of large turbine-generator foundations are to maintain the proper shaft alignment and to limit the vibration of the machine during operation....
Seismic Rehabilitation of Sardis Dam
Extensive subsurface investigation of the embankment dam revealed the existence of a weak layer of silt and soft clay in the original topstratum clay underlaying the upstream shell of...
MASSPORT Modernization
Construction began last fall on the Massachusetts Port Authority (MASSPORT) upgrade of the 50-year-old Paul W. Conley Terminal in Boston. When completed in 1994, this timber-pile-supported...
Plastic Piling
Composite plastic and steel piles are gaining acceptance throughout the United States. The evolving technology has produced a unique product which solves several problems related to use...
Hydrogeochemical Site Investigations by Teollisuuden Voima Oy, Finland
Groundwater samples collected from cored boreholes (500-1000 m), borehole wells and multilevel piezometers in crystalline bedrock have been characterized and classified. The reference...
Estimation of Water-Filled and Air-Filled Porosity in the Unsaturated Zone, Yucca Mountain, Nevada
The responses of density and dielectric logs are formulated in terms if the matrix properties, air-filled porosity and water-filled porosity. Porosity values obtained from logs from borehole...
Borehole Security on the Yucca Mountain Project
A borehole security plan was developed and is being implemented to address safety, environmental protection and restoration, waste isolation, and security concerns related to boreholes...
Heat Transfer in Vertical Concentric Cylinders in a High Level Nuclear Waste Repository
