Abstract: An 18.2-ha coal tailings impoundment that reached full capacity in 1989 has since been undergoing reclamation activities. The impoundment is sectioned into coarse, intermediate, and fine tails regions. The fine tails region, ...

Abstract: In situ ground freezing with liquid nitrogen can be an excellent technique for obtaining high quality undisturbed samples from a wide range of loose sand deposits, with their in situ conditions preserved. This paper describes ...

Abstract: This study was carried out to investigate organic and inorganic contaminant removal from melting spray ice produced from aerated stabilization basin treated pulp mill wastewater and the oil sands tailings pond water. The ...

Abstract: Spray freezing technology has been used in ice building construction in cold regions and artificial snow making. The spray freezing process involves heat and mass transfer and ice nucleation. The freezing temperature of ...

Abstract: A long-term pile load testing program was completed at two distant early warning (DEW) line sites; two piles were embedded into a tabular ice body, and three in a saline fine-grained soil. The piles were loaded in compression ...

Abstract: The influence of enlarging the base of a pile on the total and end bearing capacities of a pile in ice-rich permafrost is evaluated along with the principles used to evaluate the total capacity of uniform diameter and ...

Abstract: This paper introduces a method for estimating the scour in cohesive soils produced by a submerged vertical circular turbulent impinging jet. Determining scour in cohesive soils is a complex problem, partly because the clay ...

Abstract: The initial state of a sand, defined by the void ratio and effective mean normal stress, can be used to predict its large-strain response. Laboratory studies have shown that the shear-wave velocity of a sand is controlled ...
