Keeping Sand at a Standstill
Construction of roads, railroads, pipelines and other facilities removes the native vegetation from sand dunes. As a result, sand movement starts and entire dunes may become active. This...
Optimization for Overall Stability
This paper synthesizes design of trusses for linear stability constraint as an optimization problem where linear stability is defined as a generalized eigenvalue problem and presents a...
A Microcomputer Program for Bearing Capacity Analysis
The objective of this paper is to introduce an IBM/PC/XT/AT microcomputer program for the Bearing Capacity Analysis of Shallow Foundations. The program incorporates the bearing capacity...
The Middletown (CT) Riverfront Development Plan
Middletown is strategically located on the banks of the Connecticut River in the central part of Connecticut. Middletown has a tradition as a maritime center. During the seventeenth and...
Recent Developments in Structural Optimization
This publication contains seven papers that emphasize the recent findings of mathematical formulations, numerical results, and algorithms in structural optimization. Among them, two deal...
Soil Nailing a Wall
Soil nailing is the reinforced-earth idea (in which the earth must be backfilled behind the wall) applied to cut situations. Soil nails are an inexpensive post-tensioned tieback, consisting...
Cut-and-Fill Becomes Cut-and-Drain
The U.S. Navy's facility in Subic Bay, Philippines, is in a mountainous area which experiences 182 inches of rain per year. These factors plus weak soil, made necessary an...
Ground Freezing for Construction
For almost a century, freezing has been used successfully as an art to stabilize ground and control groundwater. First employed by the mining industry in Europe, it has since been widely...
Frame Moments with the Takabeya Method
The Takabeya method of frame analysis, based on the same slope-deflection equations as the Hardy-Cross system, has the advantage of requiring much less memory and fewer computations than...
China Builds Record Bridge
China's Hanjiang Railway Bridge has a 1,000 ft (305 m) long main box girder and is the longest bridge of its type in the world. The steel box girder bridge is built with a...
Geotechnical Aspects of Strontia Springs Arch Dam
The bedrock at the Strontia Springs damsite consists of generally excellent quality granitic and metamorphic rock, except for a wide shear zone located beneath the dam in the lower valley...
A Contractor Looks at Slope Protection for Arctic Offshore Artificial Islands
Some thirty artificial gravel islands for oil and gas drilling/production have been built in the Beaufort Sea since early 70's. Protection of slopes of the islands and causeways...
Influence of Artificial Island Side-Slopes on Ice Ride-Up and Pile-Up
An artificial island slope protection scheme must be able to inhibit ice ride-up and pile-up in order to minimize operational interruptions. The prediction of ice ride-up and pile-up mechanisms...
Ice Forces Due to Impact Loading on a Sloping Structure
Two approximate methods are presented for determining Dynamic Magnification Factors due to floe impact on sloping structures. Some of the physical processes involved are treated simplistically,...
Ice Loads on Structures With Compound Slopes
Many of the offshore drilling structures proposed for use in the Arctic have sides with multiple slopes. Sloping walls are used at the waterline to cause the ice sheet to fail in bending...
Borrow Resource Studies in Near-Shore Areas of Alaska's North Slope
Innovative and cost-effective techniques are utilized in the exploration and analysis of near-shore sources of sand and gravel on Alaska's North Slope. High quality sources...
Deep-Water Platform Solutions for the Navarin Basin
The environmental conditions prevailing in the Navarin Basin may impose limitations on the type and shape of production, storage and loading structures. The magnitude of the wind and wave...
Structural Solutions for the Enhancement of Gravity Foundations on Very Soft Arctic Soils
Very soft soils in several offshore Arctic areas cause a major concern in the design of gravity foundations, particularly in view of the high magnitudes of ice loads. Preliminary studies...
Improving Arctic Seafloor Soil Stability
Soft, low strength soil layers at or beneath the Beaufort seafloor mean that soil strengthening may be necessary to ensure the stability of oil exploration and production structures under...
Seabed Strengthening in the Arctic by Deep Mixing
Improvement of soft soil sites in the Beaufort Sea would increase the versatility and usefulness of bottom-founded gravity structures for both mobile drilling units and permanent production...
