Impact of Multiaxial Propulsion System of Machine-and-Tractor Units on Soil Density

Сельскохозяйственные машины и технологии, 2018
Use of the powerful tractors as a part of the machine-and-tractor units (MTU) is limited to high impact of their propellers (deformers) on the soil. The increase in tractor weigh and the multiple MTU passes result in overconsolidation of the soil.

The deformation behavior of soil mass in the subsidence region of Beijing, China [PDF]

Proceedings of the International Association of Hydrological Sciences, 2015
Land subsidence induced by excessive groundwater withdrawal has been a major environmental and geological problem in the Beijing plain area. The monitoring network of land subsidence in Beijing has been established since 2002 and has covered the ...

Perbaikan Tanah Dasar Jalan Tol Semarang – Demak Menggunakan Bahan Aditif Dan Perkuatan Kolom Stabilisasi

Rekayasa Sipil, 2018
In Semarang there is often a flood of sea water that swamp the road. This happens because the ground is lower than the water level, load-carrying capacity is deficient. Following up on this, a new road network is needed as a toll road.

Numerical evaluation of the pipe-pile buckling during vibratory driving in sand [PDF]

, 2019
The buckling of steel pipe piles during vibratory driving is numerically studied using the Multi-Material Arbitrary Lagrangian-Eulerian (MMALE) method. This method handles the large soil deformations that occur during pile driving and other geotechnical ...

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Deformation of layered soil

Strength of Materials and Theory of Structures
One of the consequences of the aggression of the russian federation in Ukraine is a change in the properties of the surface layers of some regions of the soil. Construction of structures in such areas must be carried out considering the above. In order to create prerequisites for taking into account the artificially created layering of the soil, an ...

Changes in Water Infiltration after Simulated Wetting and Drying Periods in two Biochar Amendments

Soil Systems, 2019
Biochar impacts soil-water related processes such as infiltration and contributes to the hydrological response of catchments. The aim of this work is to determine the impact of wetting and drying conditions on the infiltration behavior of two biochar ...
