Active earth pressure of 3D earth retaining structure subjected to rainfall infiltration

Engineering Geology, 2021
Abstract Rainfall infiltration is a key factor that determines the active earth pressure on an earth-retaining structure. Previous investigations on the stability of earth retaining structures were mainly conducted under the assumption that the backfills was dry, saturated, or subjected to a steady unsaturated flow, ignoring the time-varying ...

An improved method of active earth pressure on rigid retaining wall under movement modes considering arching effects

International journal for numerical and analytical methods in geomechanics (Print), 2022
Both wall movement mode and soil arching are important to the active earth pressure on rigid retaining wall, but the method of active earth pressure under wall movement modes considering arching effects is yet to be studied.

Static and dynamic active earth pressure

Geotechnical and Geological Engineering, 1996
The dynamic active earth pressure on retaining structures due to seismic loading is commonly obtained by using the modified Coulomb's approach which is known as the Mononobe-Okabe method. This method has generally been used for cohesionless soils only. A general solution for the determination of total (i.e.

Upper bounds for the 3D seismic active earth pressure coefficients

Geotechnique Letters, 2022
A numerical implementation of the upper bound theorem of limit analysis is applied to determine 2D and 3D active horizontal earth pressure coefficients considering seismic actions through a horizontal seismic coefficient.

Analytical solution of general axisymmetric active earth pressure

International Journal for Numerical and Analytical Methods in Geomechanics, 2008
AbstractThe active earth pressure of circular excavation is expected to be smaller than the plane strain active earth pressures. Using the plane strain active earth pressure coefficients in design is obviously a conservative approach. In this paper, an analytical solution is developed to determine the active earth pressure on inclined rough circular ...

Active Earth Pressures for Unsaturated Retaining Structures

Journal of Geotechnical and Geoenvironmental Engineering, 2015
AbstractAlthough commonly ignored in classical earth pressure methods, precipitation-induced failures in retaining structures highlight a need for explicit consideration of negative pore pressures or matric suction. Changes in the degree of saturation in the backfill can significantly affect active earth pressures.

Displacement‐Dependent Active Earth Pressure on Retaining Wall in Cohesive Soil: DEM Simulation and Theoretical Analysis

International journal for numerical and analytical methods in geomechanics (Print)
Accurately assessing active earth pressure is crucial for the design and stability analysis of retaining structures in geotechnical engineering. This study investigates the displacement‐dependent active earth pressure on retaining walls in cohesive soil ...
