Active earth pressure against flexible retaining wall for finite soils under the drum deformation mode. [PDF]

Sci Rep, 2022
A reasonable method is proposed to calculate the active earth pressure of finite soils based on the drum deformation mode of the flexible retaining wall close to the basement’s outer wall.

Real-Time Dynamic Earth-Pressure Regulation Model for Shield Tunneling by Integrating GRU Deep Learning Method With GA Optimization

IEEE Access, 2020
This paper proposes an intelligent framework to predict and automatically regulate earth pressure using a deep learning technique during earth pressure balance shield tunneling. A prediction model was proposed by integrating a new cost function (relative

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The classical earth pressure theory assumes a semi-infinite soil behind the wall, which is no longer applicable to the problem of earth pressure in the case of finite soil.

A generalised analytical framework for active earth pressure on retaining walls with narrow soil

Geotechnique, 2022
Active earth pressure on retaining structures supporting a narrow column of soil cannot be properly analysed using Coulomb's theory. Finite element limit analysis (FELA) shows that the soil form multiple failure surfaces if the soil column is ...

Significance of flow rule for the passive earth pressure problem

Acta Geotechnica, 2021
Determination of earth pressures is one of the fundamental tasks in geotechnical engineering. Although many different methods have been utilized to present passive earth pressure coefficients, the influence of non-associated plasticity on the passive ...

The stability of subducted glaucophane with the Earth’s secular cooling

Nature Communications, 2021
Along the cold subduction geotherm, glaucophane remains stable down to pressure and temperature (P–T) conditions of ca. 240 km depth, whereas under the warm subduction geotherm, it dehydrates and breaks down into pyroxenes and silica between ca.

Superionic effect and anisotropic texture in Earth’s inner core driven by geomagnetic field

Nature Communications, 2023
Earth’s inner core is heterogeneous and anisotropic. A new study based on computational simulation reveals the presence of ionic hydrogen flux in iron crystals, driven by the dipole geomagnetic field, which promotes the formation of observed inner core ...
