The geomechanical properties of soils treated with nanosilica particles

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2023
This study examines the effect of nanosilica (NS) additive to improve the mechanical properties of clay, clayey sand, and sand. The engineering properties of the soils were investigated through Atterberg limits, compaction, unconfined compression ...

Booming Sand Dunes [PDF]

open access: yes, 2010
"Booming" sand dunes are able to produce low-frequency sound that resembles a pure note from a music instrument. The sound has a dominant audible frequency (70-105 Hz) and several higher harmonics and may be heard from far distances away.

The influence of incorporating a forecutter on the performance of offshore pipeline ploughs [PDF]

open access: yes, 2013
Installation of offshore pipelines in the seabed can be efficiently achieved using pipeline ploughs. Increased efficiency may be achievable through incorporating a smaller forecutter in advance of the main plough share.

Effect of Sand and Sand‐Lime Piles on the Behavior of Expansive Clay Soil

open access: yesAdvances in Civil Engineering, 2021
Expansive clay soil causes serious problems to many structures due to its swelling and shrinkage during wet and dry seasons. With the existence of expansive soil in Ahkmim new city, Sohag governorate, Egypt, some light buildings, road pavements, and buried pipelines have shown some damage.

Sand fraction is not suitable for forensic investigations in subtropical soils [PDF]

open access: yesRevista Brasileira de Ciência do Solo, 2020
Most of the forensic comparison of soils has focused on the clay and silt fractions at the expense of the coarser particles. This study aimed to test the potential of elemental and physical analyses in the sand fraction from subtropical soils to ...

Soil conditions and bounds to suction during the installation of caisson foundations in sand [PDF]

open access: yes, 2014
Suction installation of caisson foundations is widely adopted in the oil offshore industry. When such foundations are installed in sand, seepage conditions are known to play a pivotal role in the installation process.
