Seismic performance of gravity retaining walls
Earthquake Engineering & Structural Dynamics, 2023AbstractIn the present study, the seismic performances of gravity retaining walls having both inclined back side and inclined backfill were investigated under sinusoidal acceleration excitations using series of shaking table tests on 750 mm height physical model.

Seismic Behavior of Gravity Retaining Walls
GeoFlorida 2010, 2010Finite Element Method has been used to investigate the interaction of soil-retaining wall under the effect of earthquake induced forces. By numerical analysis the behavior of modeled gravity retaining walls have been evaluated under the effect of four real earthquake spectra.

Seismic Behavior of Gravity Retaining Walls
Journal of the Geotechnical Engineering Division, 1979First, the paper shows that in order to use the quasi-static Mononobe-Okabe analysis for the prediction of earthquake dynamic forces on a gravity retaining wall, wall inertia effects must be included. Second, a design procedure is developed in which the designer chooses an acceptable level of wall displacement: he then computes the design wall weight ...

Seismic Response of Gravity Retaining Wall
2020The behavior of retaining wall during an earthquake is a topic of major concern nowadays due to its grave consequences. IS 1893 adopts the force-based pseudo-static method for the design of retaining walls under seismic condition, which incorporates the additional seismic force into the static Coulomb’s theory.

Calibration of resistance factors for gravity retaining walls
Georisk: Assessment and Management of Risk for Engineered Systems and Geohazards, 2022Geotechnical design codes have been migrating from the traditional allowable stress design towards load and resistance factor design (LRFD). In this paper, calibration of the geotechnical resistance factors for sliding and overturning limit states of gravity retaining walls is performed using a reliability-based method.

Seismic stability analysis of gravity retaining walls
Soil Dynamics and Earthquake Engineering, 2010A new approach based on the category of upper bound theorem of limit analysis is presented in this study to consider the seismic stability of gravity retaining walls. The retaining wall and the backfill soil were taken as a whole system. For a translational failure mechanism assumed, formulas are provided to calculate directly the yield acceleration ...

Earth pressure behind a gravity retaining wall
International Journal for Numerical and Analytical Methods in Geomechanics, 1989AbstractThis paper presents the results of an investigation of the static earth pressure behind a gravity wall with dry cohesionless backfill. A comparison is made between the results of finite element analyses and those of several experimental studies on wall models.

Probabilistic analysis of gravity retaining wall against bearing failure
Asian Journal of Civil Engineering, 2023Machine learning (ML) models have been extensively used in the stability check of gravity retaining wall. They are renowned as the most capable methods for predicting factor of safety (FOS) of gravity retaining wall against bearing failure. In this work, FOS against bearing is predicted based on extreme gradient boosting (XGBoost), random forest (RF ...
