The Influence of Soil Saturation and Soil Strain on Landslides

International Journal For Multidisciplinary Research, 2023
Landslides are the movement of masses of rock, regolith and soil from high to low places due to the influence of gravitational forces, due to the weakness of the soil structure when saturated. Humidity on a certain slope is an initial indication of a landslide.

Lower shakedown limits of layered road structures under moving harmonic loads

Yantu gongcheng xuebao, 2022
The shakedown limits of layered road structures subjected to a moving harmonic load are studied. The inverse Fourier transform and the numerical integration are used to obtain the dynamic responses of a three-dimensional layered road structure in the ...

Effect of soil saturation on denitrification in a grassland soil [PDF]

Biogeosciences, 2017
Abstract. Nitrous oxide (N2O) is of major importance as a greenhouse gas and precursor of ozone (O3) destruction in the stratosphere mostly produced in soils. The soil-emitted N2O is generally predominantly derived from denitrification and, to a smaller extent, nitrification, both processes controlled by environmental factors and their interactions ...

Dynamic response of composite linings of shallowly buried tunnels in saturated soils subjected to incidence of plane Rayleigh waves

Yantu gongcheng xuebao, 2022
Based on the Biot wave theory and the Fourier-Bessel series expansion method, a mechanical model for scattering of composite linings of shallowly buried tunnels in saturated soils subjected to incidence of plane Rayleigh waves is established.

Effects of Saturation on Shear Strength of Soils

Soils and Foundations, 1991
ABSTRACT In an attempt to study effects of saturation ratio on the strength parameters of partly saturated soils, several series of triaxial compression tests were conducted on samples of silty sands to silty clay which were recovered from several sites of landslides triggered by heavy rainfalls in recent years.
