Based on the authors' theoretical modeling framework of the saturated freezing soil, this paper further discusses the air phase in the unsaturated freezing soil in two ideal situations: air in the soil is linked to the atmosphere (the open porous medium) and air in the soil is isolated from the...
In order to determine the efficiency of on-site bioremediation of diesel contaminated subAntarctic soils, a pilot biopiles study was initiated in January 2006 with a selected soil of The Grande Terre (Kerguelen Archipelago, 69° 42′E–49° 19′S). Each 4 kg biopile received 180 g of diesel...
Many of the broad cold regions are located in seismic active zones. Little research has been conducted to investigate the seasonally frozen soil effects on the seismic performance of bridge structures. An analytical investigation of the seasonally frozen soil effects on the seismic behavior of a...
Frozen soils were observed in situ using fluorescence microscopy, and the suitability of applying 5-sulfofluorescein diacetate dye (sFDA) to study frozen soil was verified. We examined the temperature dependency of microbial activity in soil around 0 °C using the fluorescent area as an index....
Under the impact of potential climate warming and human engineering activities, the Embankment with Crushed Stone Slope Protection (ECSSP) needs further countermeasures to protect the underlying permafrost along the Qinghai–Tibet railway in warm (− 1 to 0 °C) permafrost regions according to...
The strength of freeze-bonds in-between blocks in first-year ridges has been investigated through field and laboratory tests. A series of small scale field tests with submerged ice blocks were carried out in Adventfjorden on Svalbard in March–April 2005. An opening was made in the landfast...
