Abstract
This paper presents various design and construction aspects of stress relief mechanically stabilized earth (MSE) walls and challenges faced during the construction of gabion face MSE walls in St. Anthony Falls (I-35w) Bridge. The bridge is supported by three lane-based piers standing 70 ft high. On either side of the bridge, the approach embankments are constructed using the Terramesh System, Maccaferri Gabion face MSE walls. The abutment along the 2nd Avenue bridge on the North end of the main bridge is not designed to take horizontal earth pressure demanding a stress relief wall. These stress relief walls are constructed using the Terrawall System.
