Analysis of a Production Well Through Sediments Containing Gas Hydrates
In some of the petroleum reservoirs recently discovered north of the Arctic Circle, production wells extend through thick permafrost. Several authors have reported zones of gas hydrate...
Santa Fe's Mobile Arctic Drilling Barge
There is a need for mobile units that can operate year-round in shallow Alaskan waters south of the Bering Strait for exploratory drilling and/or early production. Santa Fe has completed...
The Deformation Properties of Warm Underocean Permafrost
Two quasi-conventional incremental pressuremeter tests were carried out on man-made specimens of 'warm' ( minus 3 degree C) frozen, saturated sand. Instead of...
Effects of External Loadings on Large-Diameter Buried Pipelines
Development of oil and gas resources in the far north has involved extensive use of buried steel pipelines. Buried pipelines, particularly onshore, are frequently subjected to heavy superimposed...
Cyclic Multiaxial Cubical Cell Experiments on a Norton Sound Silt
A servo-controlled multiaxial cubical test apparatus has recently been used to investigate the behavior of the foundation soil for a gravity structure in Norton Sound of the Alaska Outer...
Analysis of Liquefaction Potential of Hydraulically Placed Subsea Berms
The use of hydraulically placed sand for the construction of artificial islands for hydrocarbon exploration in the Beaufort Sea has necessitated detailed geotechnical evaluations of their...
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...
SAV Reestablishment Results?Upper Chesapeake Bay
In the Susquehanna Flats area of the upper Chesapeake Bay, six submersed aquatic plant species were used to test the feasibility of transplanting SAV into sites which were previously vegetated,...
Earth Pressure on Underground Concrete Pipe in a Field Test
The cause of cracking at the sheetpile extraction in concrete pipes buried by the open excavation method was investigated by loading tests on the pipe and a field test carried out by Osaka...
Earth Pressure on Underground Rigid Pipe in a Centrifuge
A series of centrifugal model tests on underground pipes that simulate the actual construction process were carried out to investigate the earth pressure concentration onto the pipe (particularly...

Design Considerations for Wind Loadings
The application of reliability concepts to the treatment of wind loadings on structures has increased in the past several years. Advances have been made in assessing the various uncertainties...
Seismic Analysis of Horse Creek Dam, Hudson, Colorado
On April 8, 1981, six days after a Richter magnitude 4. 0 earthquake, inspectors from the Colorado State Engineer's Office discovered a small crack in outboard side of Horse...
Creep of a Strip Footing on Ice-Rich Permafrost
Creep settlement tests were performed on a strip footing founded on the surface of ice-rich aeolian silt permafrost. The tests consisted of applying four step loadings to a 10 in. (25....
Predicted and Measured Performance of a Foundation
The predicted and measured short term foundation behavior of a 28 story building in downtown San Antonio, Texas is reported. The soil is a stiff to hard clay and clay shale. The design...
Geotechnical Behavior of Underreams in Pleistocene Clay
Enlarged bases are often constructed in cylindrical drilled-and-cast-in-situ foundation elements (footings, bored piles) to increase their capacity. Enlarged bases that are cut mechanically...
Acid Deposition in the Wind River Mountains
National attention has been focused on the discovery of acidified lakes in the Adirondack Mountains of New York and elsewhere in New England. It is commonly believed that the West, in...
Noise and Air Blast from Construction Blasting
Noise generated by construction blasting differs from other construction noise because of its frequency content. The audible high frequency portion is accompanied by a non audible, lower...
Microcomputer Analysis of Harbor Wind Drift
A microcomputer with general-purpose spreadsheet software was used to analyze wind drift on the water surface of Quincy Bay in Boston Harbor. Wind drift is the movement of the surface...
Incorporating Graphics in Water Distribution Analysis
One area that has currently been receiving attention is the presentation of hydraulic analysis results utilizing computer graphics to display pipe network and pressure values in graphical...
