Calculation of Displacement-Dependent Active Earth Pressure for Deep Excavations in Soft Soil

open access: yesApplied Sciences, 2022
In the urban environment, there are strict control requirements for deep foundation pit deformation, resulting in earth pressure on the flexible supports often being in a nonlimiting state.

Rankine Active Earth Pressure of Unsaturated Filling under Earthquake

open access: yesApplied Sciences, 2023
The pseudo-static method was adopted to expand the application field of classical Rankine soil pressure theory to the circumstance of infinite inclined backfill acting on the retaining wall under earthquakes.

Active Earth Pressure for Sloping Finite Soil While Accounting for Shear Stress and Curved Slip Surface

open access: yesGeofluids, 2022
Calculating the earth pressure of the sloping soil having finite width behind the retaining wall is difficult for stability calculation. Thus, a novel method to calculate the active pressure of cohesionless sloping finite soil behind a retaining wall was

Dynamic active earth pressure on retaining structures

open access: yesSadhana, 2006
Earth-retaining structures constitute an important topic of research in civil engineering, more so under earthquake conditions. For the analysis and design of retaining walls in earthquake-prone zones, accurate estimation of dynamic earth pressures is very important.

Active and passive earth pressure coefficients by a kinematical approach [PDF]

open access: yesProceedings of the Institution of Civil Engineers - Geotechnical Engineering, 2002
A simple method is proposed for calculating the active and passive earth pressure coefficients in the general case of an inclined wall and a sloping backfill. The approach used is based on rotational log-spiral failure mechanisms in the framework of the upper-bound theorem of limit analysis.

Solution for Active and Passive Earth Pressure on Rigid Retaining Walls with Narrow Backfill

open access: yesApplied Sciences
For a retaining wall adjacent to rock or rigid structures, existing model test results indicate that the slip soil in the limit state can be approximated as a trapezoidal slip wedge.

Simplified Calculation Method for Seismic Active Earth Pressure of Translational Retaining Wall considering Soil Arching Effect

open access: yesShock and Vibration, 2021
At present, most seismic earth pressure theories have the limitations of complex derivation process and difficult solution. To solve these problems, considering the deflection of small principal stress caused by soil arching effect, the central arc soil ...

Orbital dynamics of "smart dust" devices with solar radiation pressure and drag [PDF]

open access: yes, 2011
This paper investigates how perturbations due to asymmetric solar radiation pressure, in the presence of Earth shadow, and atmospheric drag can be balanced to obtain long-lived Earth centred orbits for swarms of micro-scale 'smart dust' devices, without ...
