Anchor Angle and its Role on Stability of Anchored Retaining Walls

Abstract

The purpose of this research is applying PlAXIS 2D in modeling of an anchored retaining wall with different combinations of behavior of the anchored wall and prepare data base that can serve the design requirements of anchored retaining walls in Libya. The structural design of the anchored wall by PLAXIS finite element software, considers soils on the back and front of the wall as well as the soil under the wall. So, this research takes into account the effect of soil under wall on wall behavior. The effect on wall is studied in terms of wall displacement, wall bending moments, wall shear forces, and soil stresses. The effect of anchor angles by using varying soil properties, wall & anchor properties, and loads behind the wall on the wall behavior has been investigated as well. The results proved the applicability of Plaxis model in responding to different combinations of wall and soil parameters, and showed different structural behavior by the anchored wall with every change in wall and soil parameters. So, findings corresponding to different combinations of parameters were prepared for the sake of any related future research.
