Macro- and microscale gaseous diffusion in a Stagnic Luvisol as affected by compaction and reduced tillage [PDF]

, 2008
Intensification of mechanical agriculture has increased the risk for soil compaction and deformation. Simultaneously, reduced tillage practices have become popular due to energy saving and environmental concerns, as they may strengthen and improve the ...

Experimental study on the cyclic resistance of a natural loess from Northern France [PDF]

, 2009
In order to analyze the instability phenomenon observed along the Northern High Speed Line of R\'eseau Ferr\'e de France (RFF), soil blocks were taken at a site near the railway, at four different depths (1.2, 2.2, 3.5 and 4.9 m).

Design and performance evaluation of bevameter equipment

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2020
The depth of tilting in agricultural soil is 30–40 cm, which approximates the equivalent contact diameter of tires for the off-road vehicle. The soil thus tends to have an upper loose layer and a hard layer underneath, which leads to changes in the soil ...

Mechanics Model for Inclinometer Deformation in Soft Soil and Improvement of the Measurement Method

Advances in Civil Engineering, 2022
In practical engineering, data of lateral deformation in field soft soil are measured by inclinometers. Error is always present in soft soil deformation surveys due to rigidity differences and other objective factors, which means that the measured data ...

Research progress in synergistic deformation between rock mass and soil due to underground coal mining in China

Meitan xuebao
With the gradual shift of coal mining from shallow to deep and the westward shift of coal development strategy in China, the deformation between rock mass and soil due to underground coal mining in coal mining areas has become more prominent, which can ...
