Title: Challenges in the Design and Construction of MSE Walls on the Regina Bypass Project
Presentation by: Matt MacIntosh and Tatiana Rrokaj
Abstract: The Regina Bypass is the largest infrastructure project built in the City of Regina, Saskatchewan. The site for some of the structures of this project is characterized by soft clayey soils that exhibit high settlement rates. This project was constructed using Mechanically Stabilized Earth (MSE) walls with segmental panel facings. An advantage to segmental panels is their ability to accommodate high-anticipated total and differential settlements without major effects on the overall structure. The purpose of this paper is to discuss the challenges that were encountered during the design and construction phases of the project and the solutions that were followed to overcome them. Examples of challenges include high settlement rates and winter construction.
