A bstract null null The runway icing prediction is an important guarantee for the safe and efficient operation of the airport in winter. Aiming at the complex problem of airport runway icing with many factors, the grey correlation analysis method is used to study the sensitivity of runway icing to multiple parameters, and the main influencing factors of ice thickness are obtained. The kernel function and penalty function of the least squares support vector machine (LSSVM) are optimized by the im...

Abstract null null Due to the impact of global warming on sea ice cover, experimental research is required to better understand the interactions between sea ice and waves. In this study, an experiment was conducted on waves propagating through a solitary floe model, at Shanghai Jiao Tong University. The front (reflected) and rear (transmitted) wave fields and the overwash waves around the floe model with regular incident waves were investigated within a range of incident periods and steepness va...

Abstract null null Conventional de-icing methods with salts and snow removal causes considerable maintenance cost and outstanding indirect costs due to corrosion of the steel reinforcement of concrete infrastructures. Alternatively, heating systems based on Electrically Conductive Concrete (ECC) have been lately developed to reduce operational and reparation cost. The aim of this work is to develop an optimized prefabricated ECC slab with a safe level of electrical current, integrated snow senso...
Abstract null null Terrace floodbed sediments provide a key to understanding riverine flood history but to date floodbed chronologies have been limited in their temporal resolution. This study reconstructs the spring flood frequency, magnitude, and sediment delivery of the Peace and Athabasca Rivers at the Peace-Athabasca Delta (PAD), northern Canada, for the past four centuries through an algorithm that relates time to total organic matter accumulation in terrace floodbeds. The floodbed chronol...

Abstract null null Cyclic action of wetting-drying-freezing-thawing (WDFT) is an important factor for damages of canals in seasonally frozen regions, which should be taken into account for relevant studies. This paper presents details of an investigation dealing with the effects of wetting-drying-freezing-thawing cycles on the mechanical behaviors of expansive soil by triaxial tests. The results show that the WDFT cycles had a significant impact on the attenuation of expansive soil mechanical pr...

Abstract null null Ice-induced scour is a serious challenge for the subsea pipelines in the Arctic shallow waters. Estimation of the maximum pipeline deformation and its minimum burial depth can guarantee the operational integrity of these structures in the ice-prone regions. The pipeline buried below the ice keel is still threatened by subgouge soil deformation that is extended down the ice tip due to the shear resistance of the seabed soil. Determining the subgouge soil deformations is a chall...

Abstract null null Ice protective coatings could revolutionize the aviation industry as they could assist or even replace traditional ice protection systems that increase the vehicle weight and power requirements. A major problem for many potential ice protective coatings is durability. This paper explores whether erosion resistant titanium aluminum nitride coatings (TiAlN) can be made ice protective by reducing both surface roughness and coating defects (such as pin holes or scratches). Cathodi...

Abstract null null The possibility of confronting unsuitable soils in the construction site prompted the engineers to find a way to change inappropriate features of the natural soils. The process of changing the natural soil properties is referred to as soil improvement. Since the used soil from the site is exposed to sequential freeze and thawing conditions, it affects the mechanical and physical properties of the natural soil, leading to a reduction in strength and increase in volume change an...

Abstract null null Rotary clamp spacer is a prospective anti-galloping device for bundle conductor lines. The rotation-free clamp of a rotatory clamp spacer allows the connected sub-conductor rotate freely around its axis, which makes ice shape along span uniform and weakens the aerodynamic loads on the iced sub-conductors to diminish or control the galloping. In this paper, the cross-section shapes of accreted ice along sub-conductors, which are connected with rotation-free clamps of a spacer, ...
