Numerical Modeling of Thaw Penetration in Frozen Ground Subject to Low-Intensity Infrared Heating
(American Society of Civil Engineers, 2006)This research investigated the efficacy of low-intensity, radiant, infrared heating for inducing thawing in frozen ground. Specifically, the performance characteristics of a 22 kW infrared tube heater were evaluated. A ... -
Dynamic Uplift Scenarios for Floating Ice
(American Society of Civil Engineers, 2006)Three uplift scenarios in the forced dynamics of floating ice are studied. Linear, quadratic, and square-root uplift forcing functions are considered and the associated uplift displacement functions are computed numerically. ... -
Ice Stresses in Reservoirs: Effect of Water Level Fluctuations
(American Society of Civil Engineers, 2006)Ice stress, temperature, and forebay elevation data were collected over two winter seasons from the La Gabelle reservoir, located in south-central Quebec, Canada. These data suggest that large compressive stresses can ... -
Experimental Study of Ice Jam Formation Dynamics
(American Society of Civil Engineers, 2006)Ice jams pose a significant threat to human safety and property and represent one of the most dynamic of river ice processes. A key limitation in the advancement of knowledge of ice jam formation is the lack of quantitative ... -
Growth and Decay of Estuary Ice Cover
(American Society of Civil Engineers, 2006)This paper presents a new vertical 1D finite-element model to simulate the growth and decay of an ice cover (columnar ice, snow ice, slush, and snow cover consolidation) over a winter season in a partially mixed mesotidal ... -
Hydrodynamics of Mesotidal Estuary in Winter
(American Society of Civil Engineers, 2006)In this article, we quantify the effects of a standing ice cover on the hydrodynamics of a mesotidal estuary. The Portneuf Estuary, Québec, is -
Durability Characteristics of Some Assorted Rocks
(American Society of Civil Engineers, 2004)Durability characteristics of some argillaceous clastic rocks from cold regions are investigated. Two sets of experiments, namely slake durability (wet-dry) and freeze-thaw tests, were conducted on welded tuff, carbonates ... -
Modeling Impacts of Thaw Lakes to Ground Thermal Regime in Northern Alaska
(American Society of Civil Engineers, 2004)In northern Alaska, the ground is largely underlain by permafrost. Many engineering problems in this region can be attributed to the variations of ground thermal regime. Engineering projects such as construction of gas ... -
Modeling Ice Passage at Navigation Locks
(American Society of Civil Engineers, 2004)Physical and numerical models were used to assess ice passage at navigation locks, focusing on key factors such as the design of the lock filling and emptying system and the intakes to the lock filling culverts. Unconventional ... -
A New Report on Permafrost Research Needs

In situ Sea Ice Experiments in McMurdo Sound: Cyclic Loading, Fracture, and Acoustic Emissions
(American Society of Civil Engineers, 2004)The breakup of first-year sea ice plays an important role in the dynamics and thermodynamics of polar ice covers. A recent research program has studied the in situ mechanical properties of the annual ice in Antarctica to ... -
Failure in Composite Materials due to Volumetric Expansion of Freezing Moisture
(American Society of Civil Engineers, 2004)A model is developed for predicting volumetric expansion induced cracking in orthotropic composite materials due to freezing of trapped moisture in a slender rectangular flaw region. Conformal transformation and the complex ... -

Use of Simulink for Dynamic Air Quality Modeling in Interior Alaska
(American Society of Civil Engineers, 2005)Interior Alaska has indoor air quality (IAQ) issues similar to those of other far northern communities associated with long cold winters and reduced ventilation rates. We also have some interesting issues associated with ... -
Permafrost Studies in the Qinghai–Tibet Plateau for Road Construction
(American Society of Civil Engineers, 2005)Advances have been made in engineering–geological studies of roadbeds in permafrost areas of the Qinghai–Tibet Plateau. The methodology used in engineering–geologic investigations has been greatly improved and provisions ... -
In Situ Test on Cooling Effectiveness of Air Convection Embankment with Crushed Rock Slope Protection in Permafrost Regions
(American Society of Civil Engineers, 2005)An experimental air convection embankment (ACE) was constructed in Beiluhe on the Qinghai-Tibet Plateau during 2001–2003, using coarse (5–8 and 40–50 cm), poorly graded crushed rock fill material on the slope of embankment ... -
Experimental Study on the Ventiduct Embankment in Permafrost Regions of the Qinghai-Tibet Railroad
(American Society of Civil Engineers, 2005)This technical note presents an experimental study on the ventiduct embankment in permafrost regions of the Qinghai-Tibet Railroad. Two experiments were conducted in a test box and they were designed with similarity theory. ... -
Laterally Loaded Pile Study in Permafrost of Northern Québec, Canada
(American Society of Civil Engineers, 2005)This paper describes a study undertaken at Umiujaq, in northern Québec, on laterally loaded piles in permafrost subject to a constant displacement rate. Test results of bending moments, shear load, soil reaction, and pile ... -
Fabrication and Testing of Apparatus for Laboratory Simulation of Alaska Frozen Rock Encountered during Hydrate Gas Reservoir Coring
(American Society of Civil Engineers, 2004)Gas hydrates are inclusion compounds in which gas is trapped in ice. They are widely found in nature in permafrost and deep-sea sediments and hold huge potential as a methane gas resource. As a result, a National Methane ...
