Execution and Evaluation of High Capacity Caisson Load Tests in Glacial Deposits
As part of the Boston Harbor clean up project, the new 1,000 mgd Deer Island Sewerage treatment plant includes ten 240 feet high egg-shaped 'residuals' tanks. Contract documents called...
South Africa at the Crossroads
With the provisional decision to hold its first democratic elections in 1944, South Africa has reached the most crucial moment in its history, one on which its economic and social development...
Slip-Lining Solution
Grouting the annular space between a corroded sewer pipe and newly installed liner pipe is a stage of a typical sewer line rehabilitation project which contains hidden problems and difficulties....
The Big No-Dig
As part of the Boston Harbor cleanup project, engineers will have the opportunity to make a rare, side-by-side comparison of open-cut construction and no-dig technology during the Wellesley...
The Bechtel Edge
The Bechtel Group can commit personnel all over the world to seek out and scrutinize business opportunities, and the firm is usually at the top of Engineering News-Record's...
Performance of Upper Stillwater Dam
Upper Stillwater Dam was constructed with roller compacted concrete (RCC) and horizontally slipformed facing. This unique construction method for a concrete gravity dam included no contraction...
Laupahoehoe Harbor Planning, Design, & Construction
Laupahoehoe Harbor provides access to the fertile fishing grounds along the northeast or Hamakua coast of the island of Hawaii, Hawaii. The planning, design, and construction of Laupahoehoe...
A Design Manual for Coastal Fluidization Systems
This paper summarizes a recently completed design manual on fluidization systems to manage sand in the coastal environment for sand bypassing at inlets and harbor mouths and for creating...
Tackling Trapped Sediments
Crater-sink fluidization has been used to recover sediment from harbors for the past couple of decades. Can this method bypass sediment around dams and return it to eroded beaches, solving...
Motown Tunneling
When finished in 1993, Wayne County Michigan's $69 million wastewater treatment/sewer project will link outlying areas such as Dearborn with sewage treatment facilities in...
Turbulence, and Energy Loss, at Combining Pipe Junctions
Efforts to measure and describe the loss of energy at 90? sharp-edged junctions are described. The work is focussed on energy losses at discharge and area ratios for which there are no...
General Mechanism of Turbulence
By considering the vortex structures of turbulence and using the concept and theory of the pulsative convection and diffusion of instantaneous vorticity in a viscous fluid motion, the...
Evaluating Polymer Concrete Bridge Expansion Joints Using Acoustic Emission
This study is to simulate the acoustic emission (A/E) of polymer concrete bridge expansion joints subjected to controlled representative loads by a rotating test apparatus on a circular...
Joint Network Modeling and Scale Effects in Rock
Joint networks play a vital role in the mechanical and hydraulic behavior of rock masses. A realistic representation of joint geometry in rock masses and correct understanding of the mechanical...
Wave Propagation in Solids
The last fifty years have seen the development of a large number of application of the theory of wave propagation in solids to problems of interest to civil engineers. Most notable have...
Applications of Viscoelastic Damper to Jointed Structures for Seismic Mitigation
Some structures, such as dams, are built with contraction joints that might carry some small tensile stresses. Such joints are expected to open and close during an earthquake. That will...
Structural Characterization of an Articulated-Truss Joint
A first generation space crane articulated-truss joint was statically and dynamically characterized in a configuration which approximated an operational environment. The articulated-truss...
Analysis of Space Crane Articulated-Truss Joints
Three articulated-truss joint concepts for the space crane are studied to evaluate their static structural performance over a range of geometric design parameters. Emphasis is placed on...
Piping in Earth Dams of Dispersive Clay (Paper introduced by Norman L. Ryker)
In 1971 Jim Sherard was engaged to investigate the common failure of a group of Soil Conservation Service (SCS) floodwater retarding earthfill dams built between 1957 and 1970, eleven...
Stabilizing Drop Structure by Drainage Modifications
East Drain Terminal Drop Structure is located in East Drain, an open toe drain of Palmetto Bend Dam, in the tide water area of south Texas. The drop structure was threatened by piping...
