Study on Dynamic Response Characteristics of Stepped Reinforced Retaining Wall

Buildings, 2022
In order to further explore the influence of reinforcement materials laying position on the dynamic characteristics of reinforced retaining walls, based on FLAC3D finite difference methods for solving nonlinear problems, established with the same size of

Calculation of earth pressure on culvert underlying flexible subgrade

Results in Physics, 2019
To explore the influence of soil displacement around culvert on earth pressure at culvert crown, the concept of “neutral point” of culvert is proposed based on the interaction mechanism of culvert-fill-subgrade.

Redox reactions in subducted CaCO3–Fe–SiO2 as a potential source of superdeep diamond inclusions

Scientific Reports
CaCO3 is one of the most abundant carbonates at the Earth’s surface. It is transported into the mantle in substantial quantities via subducted slabs and participates in the deep mantle carbon cycle along with other mantle materials.

Relationship between earth pressure and wall displacement based on Coulomb earth pressure model

Yantu gongcheng xuebao, 2018
The magnitude of earth pressure is greatly influenced by wall displacement. Based on the viewpoint that the relationship between wall displacement and lateral earth pressure is the macroscopic embodiment of soil stress-strain behavior, the relationship ...

Weighing the ocean: Using a single mooring to measure changes in the mass of the ocean [PDF]

, 2012
Combining ocean and earth models, we show that there is a region in the central Pacific ocean where ocean bottom pressure is a direct measure of interannual changes in ocean mass, with a noise level for annual means below 3 mm water equivalent, and a ...

The Generalized Coefficients of Earth Pressure: A Unified Approach

Applied Sciences, 2019
This paper offers an extension of Cauchy’s first law of motion to deformable bodies with internal resistance with application to earth pressures. In this respect, a unified continuum mechanics approach for deriving earth pressure coefficients for all ...

Conductivity-elevated by brucite amorphization and implication for electrical anomalies in shallow subduction zones

Communications Earth & Environment
Pervasive high-conductivity anomalies in shallow cold subduction zones (40–70 km depths, corresponding to 1–2 GPa) remain unexplained by conventional mechanisms (e.g., dehydration fluids).
