Paper Title:

Optimization of Shape Design for Gravity Retaining Walls

Abstract: Gravity retaining walls are known to be relatively economic as retaining solution to the heights up to 4m. Gravity walls depend on their mass (stone, concrete) to resist pressure from behind the walls. Many shape gravity retaining walls are used; rectangular, triangular, and trapezoidal. This study focuses on finding the optimum shape design for retaining walls. The cost of the gravity retaining walls depends on the weight and the materials. In order to minimize the cost, materials of the gravity retaining walls should be minimized, which mean that the section of gravity retaining walls must be reduced. The design starts by choosing the shape of gravity walls for which the stability of the wall is checked. To study the effect of shape on minimizing the weight or volume (Area) many sections were used. In the present work the result of a numerical analysis is presented. The results show that the rectangular retaining wall shape has a large volume which in turn it has a large weight equal to100 %from the total weight ,triangular shape has 73 % from the total weight, and trapezoidal shape has 52 % from the total weight with better stability against the soil which is the most economical shape of gravity retaining walls.

Keywords: Gravity Retaining Walls, Shape, Numerical Analysis.
