Mechanically Stabilized Earth (MSE) walls are used extensively for grade-separation fill structures in many applications, e.g., highways, railways, marine, commercial, etc. To avoid adverse performance issues, design processes for an MSE wall must be tailored to specific geometry and the environment (conditions) expected over its specified lifetime. This workshop is geared towards development of a better understanding of design procedures using principles of limit states to ensure safe and serviceable MSE wall structures over specified lifetimes. More specifically, this workshop is based on the Load and Resistance Factor Design (LRFD) methodology that is a North American version of the broader Limit State Design (LSD) approach. The design principles will be explained using wall geometries with level and sloped backfill configurations. The topic of complex geometries will be introduced. The presentation ends with a brief introduction to the design philosophy for the new MSE-LASR technology that permits consideration of Local Available Sustainable Resources (LASR), i.e., non-select or marginal fills.
