Recent advances in research on the aeolian geomorphology of China's Kumtagh Sand Sea [PDF]

open access: yesAdvances in Geosciences, 2014
The Kumtagh Sand Sea in the hyper-arid region of northwestern China remained largely unexplored until the last decade. It deserves study due to its significance in understanding the evolution of the arid environments in northwestern China, and even ...

Nonlinear dynamics of Aeolian sand ripples [PDF]

open access: yesPhysical Review E, 1999
We study the initial instability of flat sand surface and further nonlinear dynamics of wind ripples. The proposed continuous model of ripple formation allowed us to simulate the development of a typical asymmetric ripple shape and the evolution of sand ripple pattern.

Study on seismic performance of aeolian sand concrete shear walls with CFST columns and concealed bracings [PDF]

open access: yesArchives of Civil Engineering
In order to promote the application of aeolian sand resources in steel-concrete composite shear wall, a kind of aeolian sand concrete shear walls with concrete filled steel tube (CFST) columns and concealed bracings is proposed in this paper.

Chloride ion transport and service life prediction of aeolian sand concrete under dry–wet cycles

open access: yesScience and Engineering of Composite Materials, 2023
In this study, the dry–wet cycle test of chloride salt was carried out on aeolian sand concrete with different contents, and the chloride ion content in aeolian sand concrete was determined by taking powder from different depths on one side of the test ...

Uplift load tests on model spread foundations in cement-stabilized aeolian sand

open access: yesYantu gongcheng xuebao, 2017
Aeolian sands are inherently very low in strength and very high in compressibility because they are loose, cohesionless and easily movable. The cement-stabilization of aeolian sand may be an alternative method to improve the mechanical characteristics of

The physics of Aeolian sand transport [PDF]

open access: yesComptes Rendus. Physique, 2015
We give a synthetic overview of the state of art of the physics of sand Aeolian transport. We first present the main ideas developed by Bagnold in the middle of the last century. We then review the recent experimental and theoretical advances made in the field and emphasize that the particle flow rate does not exhibit a cubic dependence with the air ...

Liquefaction and Reliquefaction Characteristics of Aeolian Sand Foundation Reinforced by Precast Cement Piles Based on Shaking Table Test

open access: yesGeofluids, 2022
With the continuous development of traffic construction, road engineering inevitably crosses the aeolian sand river valley area. Compared with general sandy soil and silty soil, cohesionless aeolian sand foundation has similar properties with fluid and ...
