dot.ca.govNote - Soil Nail Walls and Mechanically Stabilized Earth (MSE) Walls are not included in this Manual. Both of these types of systems are designed by other methods that can be found on-line with FHWA or AASHTO. 4.2 . LOADING . A major issue in providing a safe shoring system design is to determine the appropriate earth pressure loading diagram.
