Creep Properties of Ice: Theory and Experiment
In recent years, intensive developments in Northern regions have increased the demand for solutions to a large number of engineering problems involving ice mechanics. In particular, these...
Arctic Earth Materials for Offshore Construction in Alaska
With the exploration activities onshore and offshore and the development of production facilities, the need for granular earth materials on the North Slope of Alaska is ever present. The...
Strength and Deformation Behavior of Frozen Saline Sand and Gravel
Construction of offshore oil and gas exploration and production structures often considers the use of either sand or gravel fill materials. Fill soils exposed to the environment will progressively...
Time Dependent Material Properties Due to Solute Redistribution in Frozen Marine Soils
The design of earth structures and foundations in arctic marine environments requires the assessment of soil properties. A study is presented which investigates the change in mechanical...
Endochronic Constitutive Modeling of Frozen Soil
The static behavior of a permafrost type foundation, for a typical artificial island in the Arctic, is determined using endochronic axisymmetric finite element analysis. Endochronic constants...
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...
Geotechnical Thermal Analysis with a Microcomputer
A computer program entitled TDHC (Two-Dimensional Heat Conduction), based on finite element modelling, is capable of solving two-dimensional nonsteady-state heat conduction problems. These...
Microsilica Concrete: Properties and Applications
With the advent of microsilica concrete, a new generation of high to ultra high strength and high durability concretes have become commercially feasible and are now being specified and...
Overview of Soil and Engineering Geologic Conditions in the Beaufort, Chukchi, and Bering Seas
General soil and engineering geologic conditions that are likely to affect exploratory drilling and development activities in six Alaska OCS lease sale areas are discussed. Important conditions...
Strength-Deformation Properties of Arctic Silt
Hydrocarbon exploration and production activities in the Beaufort Sea require construction of gravity structures capable of withstanding extremely large ice loads at sites where the subsea...
Wave Induced Liquefaction and Scouring in Yukon Prodelta Silts
The scouring potential of the Yukon prodelta has been investigated. The results obtained from geologic, hydrodynamic and geotechnical considerations indicate that probable liquefaction...
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...
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...
Pile Creep Designs for Frozen Layered Profiles
A concept of relative creep stiffness suitable for the evaluation of the long-term, uniform creep behavior of non-ice type, frozen soils is presented. This concept extends the current...
Creep Rate Analysis of Pile Load Test Data
The uniform creep behavior of five driven piles and one slurried pile based on pile load test data are presented and analyzed. The incremental static load tests carried out by ARCO, Alaska...
MILHY?A Microcomputer Based Hydrologic and Hydraulic Model
MILHY is an interactive, single event, lumped parameter model used to estimate streamflows and water surface profiles. The model was designed for use on basins less than approximately...
Use of Rayleigh Waves in Liquefaction Studies
The Spectral-Analysis-of-Surface-Waves method is a new seismic method for efficient determination of shear wave velocity in situ. Vertical impacts applied to the ground surface are used...
Computer-Aided Studies of Complex Soil Moduli
Low-cost microcomputers and new electronic components make it possible to measure accurately the phase and amplitude of mechanical waves in the frequency domain at a small fraction of...
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....
