Aiming at the assessment of accidental snow loads for the design of structures, a new approach to the analysis of exceptional snowfalls is suggested. The analysis incorporates both the attitudes of civil engineering and climatology on this natural phenomenon. Analysing the records of snow load...
A new instrument for remote ice detection and thickness measurement is described. It incorporates two optically based technologies that give it capability to measure the thickness of clear or foggy layers of solid or liquid on surfaces. The device is capable of measurements on moving surfaces...
Clapeyron equation can be applied in freezing soil to describe the relationship among temperature, water pressure and ice pressure when ice and water coexist in phase equilibrium. The mathematical deduction shows that the driving force that makes the unfrozen water in soil moves from high...
In situ burning of oil spills in the Arctic is a promising countermeasure. In spite of the research already conducted more knowledge is needed especially regarding burning of weathered oils. This paper uses a new laboratory burning cell (100 mL sample) to test three Norwegian crude oils, Grane...
Deception Island, an active volcano on South Shetland Archipelago of Antarctica (62°43′S, 60°57′W), is a cold region with harsh, remote and hostile environmental conditions, what could be considered in most aspects such an analog of the Martian surface. The volcanic materials on the...
The high altitude and cold climate of the Qinghai–Tibet Plateau (QTP) means that rivers and lakes are covered by ice for 6–7 months of the year. The ice cover is a major influence on environmental and ecological conditions, since it alters the heat and energy exchange with local atmosphere,...
To solve the engineering problem and put forward new practical theoretical insights to analysis and design, in this paper, an analytical solution for the frost heaving force in cold-region tunnel has been derived firstly using the continuity equation. Thereafter, a semi-analytical method to...
