Parametric Study and Design Charts Based on Movement of Reinforced Earth Retaining Wall

摘要

The deformation resulting from wall movements is an important performance criterion for reinforced earth retaining walls. However, conventional wall design procedures are primarily stress-based and do not consider deformations explicitly. This may lead to imprecise hypothesis of the real forces in reinforcement, and conditions for soil shear failure. This paper represents numerical investigation on the compatibility behavior of reinforced earth during wall movement. The effect of reinforcement global stiffness, wall height, and soil internal angle of friction on the developed earth pressure coefficient and the maximum wall movement and the compatibility of these parameters are vital aspects in the investigation. The finite element program, ANSYS, was utilized for the analysis. The objective of this investigation is to activate parametric study in a scale adequate to get advanced design charts. The design charts were developed and their application was outlined.
