Experimental Study on Carbon Fiber Tape–Based Deicing Technology
(American Society of Civil Engineers, 2012)In cold regions, snow and ice cause serious safety problems to the transportation system. South central Alaska, particularly Anchorage, is susceptible to a number of icing events resulting from frequent freeze/thaw cycles ... -
Experimental Studies on Elastic Modulus and Flexural Strength of Sea Ice in the Bohai Sea
(American Society of Civil Engineers, 2011)This paper deals with measurements of the elastic modulus and the flexural strength of sea ice collected at nine sites in the Bohai Sea in the two consecutive winters of 2008–2010. Experimental results show that both elastic ... -
Effects of Ice-Breaking Nose Shapes on Drift Ice Impact Forces
(American Society of Civil Engineers, 2012)By using ANSYS/LS-DYNA explicit dynamical analysis software, finite element models for an ice sheet and a -
Combined Effects of Saltwater and Water Flow on Deterioration of Concrete under Freeze–Thaw Cycles
(American Society of Civil Engineers, 2011)This article outlines the combined effects of saltwater and water flow on deterioration of concrete under freezing and thawing cycles. In order to simulate the real freezing situation that concrete usually undergoes, four ... -
Classification and Comparison of Snow Fences for the Protection of Transport Infrastructures
(American Society of Civil Engineers, 2011)Blowing snow or sand transport generates serious problems, such as transport infrastructures buried under snow or sand, in many parts of the world. Some of the most important problems that snow and sand storms can cause ... -
Effect of Cold Temperature on the Chloride-Binding Capacity of Cement
(American Society of Civil Engineers, 2011)Service life of reinforced concrete structures exposed to chloride ions is closely related to the rate of chloride ion diffusion through the concrete. The determination of the apparent chloride diffusion coefficient of ... -
Effect of Ice Sheet on Stochastic Response of Offshore Wind Turbine–Seawater–Soil Interaction Systems Subjected to Random Seismic Excitation
(American Society of Civil Engineers, 2011)To investigate the effect of the presence of surrounding ice sheet on the stochastic response of offshore wind turbines subjected to random seismic excitation, this research uses a three-dimensional, numerical, finite-element ... -
Determination of Elastic Constants of Frozen Rubber-Sand Mixes by Ultrasonic Testing
(American Society of Civil Engineers, 2011)This technical note presents measurements of ultrasonic velocities of compressional and shear waves in frozen ground-rubber-sand mixtures at various mixing ratios and subfreezing temperatures. Test results showed that ... -
Numerical Assessment of Electric Roadway Deicing System Utilizing Emerging Carbon Nanofiber Paper
(American Society of Civil Engineers, 2012)Traditional deicing approaches such as salting pollute the environment and corrode reinforcing steel bars in concrete. Meanwhile, recently emerging carbon nanofiber material has improved electrical conductivity, a large ... -
Oil Sands MFT Properties and Freeze-Thaw Effects
(American Society of Civil Engineers, 2012)This paper presents a framework for combining the chemistry and mineralogy of oil sands mature fine tailings (MFT) along with geotechnical knowledge of freeze-thaw processes, large strain consolidation and MFT behavior to ... -
Stochastic Modeling of Snow Loads Using a Filtered Poisson Process
(American Society of Civil Engineers, 2011)The Bernoulli pulse process has been used in the past for modeling snow loads. However, it is not an appropriate model for heavy snow-load areas as the snow accumulation cannot be simulated, which may lead to an underconservative ... -
Three-Dimensional Nonlinear Analysis for the Cooling Characteristics of Crushed-Rock Interlayer Embankment with Ventilated Duct along the Qinghai-Tibet Expressway in Permafrost Regions
(American Society of Civil Engineers, 2010)The crushed-rock embankment and duct-ventilated embankment have been used as effective cooling measures to protect permafrost underlying the Qinghai-Tibet Railway from thawing in China. These two cooling techniques are not ... -
Seasonally Frozen Soil Effects on the Seismic Site Response
(American Society of Civil Engineers, 2011)Several large-magnitude earthquakes, including the Prince William Sound earthquake of March 1964 and the Denali earthquake of November 2002, occurred in the state of Alaska and caused considerable damages to its transportation ... -
Pipe Heating System with Underground Water Tank for Snow Thawing and Ice Prevention on Roads and Bridge Decks
(American Society of Civil Engineers, 2011)In order to prevent traffic accidents on snow-covered bridge decks, the writers developed a new pipe heating system that uses only groundwater stored in a large underground tank. The underground tank provides geothermal ... -
