Using Micropiles to Improve the Anzali's Saturated Loose Silty Sand
, 2017 Today, with the daily advancement of geotechnical engineering on soil improvement and modification of the physical properties and shear strength of soil, it is now possible to construct structures with high-volume and high service load on loose sandy ...

Journal of Quaternary Science, EarlyView.ABSTRACT The northern European distal cryptotephra framework is constantly developing both in terms of identification of new tephra horizons and improved age constraints for the already well‐established tephra marker horizons. However, many prehistoric tephra layers have only been dated by the radiocarbon method, with its inherent problems.

Stabilization of problematic silty sands using microsilica and lime
THE BALTIC JOURNAL OF ROAD AND BRIDGE ENGINEERING, 2015 In this study, to stabilize problematic silty sand soils, Microsilica-Lime admixture was used as an additive. Various samples containing 0, 1, 2, 5, 10 and 15% (by weight) Microsilica and 0, 1, 3 and 5% (by weight) Lime were prepared. To investigate the role of the studied additives on the stabilization of the sandy soils, unconfined compressive ...

Journal of Quaternary Science, EarlyView.ABSTRACT Victoria Cave, north Yorkshire, England, contains a long sequence of Pleistocene clastic sediments and calcite flowstones. Earlier work, using U–Th dating, established that the flowstone units formed in interglacial stages corresponding to Marine Isotope Stages (MIS) 13, 11, 9, 7 and 5.

Characterization of crude bacterial urease for CaCO₃ precipitation and cementation of silty sand
, 2020 Biocementation catalyzed by ureolytic bacteria or enzyme urease is a promising technique for the treatment of liquefiable soil. Silty sand is often encountered in natural conditions and is often prone to earthquake liquefaction.

Journal of Quaternary Science, EarlyView.ABSTRACT Glacial Lake Fraser, which formed in British Columbia against the retreating Cordilleran Ice Sheet, stored ~520 km3 of water before its near‐total drainage into the Salish Sea during an outburst flood event. Despite the impact of the outburst flood on sediment transport and landscape evolution in the Fraser River valley, its peak discharge and

A critical state constitutive model for clean and silty sand
, 2018 The mechanical behavior of silty sand is highly dependent on the percentage of fines in addition to the packing density and confining pressure. Properly modeling the diverse behavior of silty sand remains an area of difficulty and uncertainty. This paper

Quantifying user variability in the traditional X‐ray ice‐rafted‐debris counting technique
Journal of Quaternary Science, EarlyView.ABSTRACT The flux of icebergs is most commonly constrained in the palaeo‐record by manually counting gravel clasts in sediment core X‐ray images—a trusted method in Quaternary science and palaeoceanography for nearly 40 years. In this study, we explore the reproducibility (user consistency and between‐user variability) of the traditional clast‐counting
