Field Study on Earth Pressure of Finite Soil Considering Soil Displacement

Applied Sciences, 2022
The classical earth pressure theory assumes a semi-infinite soil behind the wall, which is no longer applicable to the problem of earth pressure in the case of finite soil.

Thermodynamic Properties of MgAl₂O₄ Spinel at High Temperatures and High Pressures

Crystals, 2023
Thermodynamic properties of MgAl2O4 spinel are significant in understanding the phase relations of the Earth’s crust and upper mantle, but available values from experimental measurements are limited at ambient pressure conditions to date.

Lateral earth pressure on rigid retaining walls with EPS deformable geofoam inclusions

Yantu gongcheng xuebao, 2019
The finite difference program, FLAC3D, is used to model the rigid retaining wall with EPS (expanded polystyrene) deformable geofoam inclusions, and the lateral earth pressure on the wall is obtained from numerical results. The at-rest state, active state

Deep carbon cycle constrained by carbonate solubility

Nature Communications, 2021
Carbonate mineral aqueous solubility decreases as carbonates become more Mg-rich during subduction. Coupled with regional variations in amounts of carbon and water subducted, this explains discrepancies in estimates of carbon recycling, suggesting that ...

Reactive formation of magnesiowüstite at the lunar core-mantle boundary

Nature Communications
Seismological and geodetic data indicate that the lunar core-mantle boundary (CMB) exhibits a well-defined low-velocity zone (LVZ) with a combination of anomalous seismic velocities and density that remain unexplained.

Earth pressure and stability of deep arch tunnel with straight wall in cohesive strata

Yantu gongcheng xuebao, 2017
The limit analysis method is adopted to study deep arch tunnel with straight wall in cohesive strata based on the shear failure theory. Firstly, a theoretical model for ruptured zone in the deep arch tunnel is established based on loading tests. And then
