Development of a generalised formula for dynamic active earth pressure

open access: yesGéotechnique, 2010
The Mononobe–Okabe method is widely used in practice to estimate dynamic active earth pressure. The method, derived from Coulomb's theory, cannot account for the effect of cohesion and hence cannot be used for a cohesive backfill. In addition, the effect of wall adhesion and external load cannot be taken into account. This paper develops a new general

Coefficients of active earth pressure with seepage effect

open access: yesCanadian Geotechnical Journal, 2012
A calculation method for the active earth pressure on the possibly inclined face of a retaining wall provided with a drainage system along the soil–structure interface is presented. The soil is cohesionless and fully saturated to the ground surface. This situation may arise during heavy rainstorms.

Evaluation of active earth pressure by the generalized method of slices

open access: yesCanadian Geotechnical Journal, 1998
The generalized method of slices, commonly used in slope stability analysis, can be extended to determine active earth pressures applied to various types of supports. The governing force and moment equlibrium equations are given. In a similar manner to slope stability analysis, the methods of optimization are used to define the critical slip surface ...

Comparative study of different theories on active earth pressure

Journal of Central South University, 2012
Determination of distribution and magnitude of active earth pressure is crucial in retaining wall designs. A number of analytical theories on active earth pressure were presented. Yet, there are limited studies on comparison between the theories.

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.

Pseudo-Dynamic Approach of Seismic Active Earth Pressure Behind Retaining Wall

open access: yesGeotechnical and Geological Engineering, 2006
Knowledge of seismic active earth pressure behind rigid retaining wall is very important in the design of retaining wall in earthquake prone region. Commonly used Mononobe-Okabe method considers pseudo-static approach, which gives the linear distribution

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.

Generalized Coulomb Active‐Earth Pressure for Distanced Surcharge

Journal of Geotechnical Engineering, 1994
Earth‐pressure problems are of great interest in geotechnical engineering and closed‐form solutions for evaluating the active‐earth pressure are widely used in the design of retaining structures. The note presents a closed‐form solution based on the Coulomb‐failure wedge for the case in which a surcharge is applied a certain distance from the wall ...
