Abstract
A mechanically stabilized earth (MSE) retaining wall is a type of soil retaining structure which utilizes reinforcements fixed to a facing system and placed in layers within the backfill. The wall resists the earth pressure by the friction between the backfill and reinforcement. The major advantages of an MSE Wall over a conventional retaining wall are to allow economical construction, especially in unfavorable situations such as higher wall height or soft ground conditions. In order to encourage students to practice a design and experience practical issues during the design and construction of a geotechnical structure, the American Society of Civil Engineers (ASCE) Geo-Institute organizes an annual national student competition. The ASCE Geo-Institute Geo-Wall Competition consists of designing and constructing an MSE wall by changing the design requirements, loading conditions, and construction materials every year but using the least amount of Kraft paper for the reinforcements to withstand a certain vertical and horizontal surcharges. This year, the goal was to design a 3D MSE wall that would withstand 50 lb of vertical load and 20 lb of horizontal load. During the design process, factors such as tensile failure and pullout failure of the reinforcements should be considered. A stable wall can be designed by modifying the width and thickness of the reinforcements, as well as the spacing of reinforcements and the proper compaction of the backfill. Once the model MSE Wall has been constructed it is judged on the following criteria: construction time, stability, displacement and deformation, weight of the reinforcements, and other factors that will be discussed later in the poster.
Program Description
Our team designed and built a model mechanically stabilized earth (MSE) wall. The goal is to construct an MSE wall that can withstand a 50 lb load on top of the wall and a 20 lb hanging weight in front of the wall, with a minimal amount of reinforcement material.
