Design Manual for Segmental Retaining Walls 3rd Edition 5th Printing

Reinforced SRW systems are composite-facing, mechanically stabilized earth (MSE) retaining wall structures that have unique features and design requirements that are addressed in detail in this guideline. The design methodologies contained within allow the engineer to analyze the influence of all components of the SRW system on wall performance. Special considerations are included for surface and subsurface drainage, water management and water control structures, and other important design considerations.

The first edition of this publication was published by NCMA in 1993 — with a second one in 1997. Since then, there have been significant changes in the state-of-knowledge regarding mechanically stabilized earth (MSE) and SRWs. These changes have been incorporated into this, the third edition of this design manual, which provides a standardized engineering approach for the analysis and design of SRWs. It also provides generic design guidelines for them, gravity structures as well as geosynthetically reinforced soil segmental retaining walls.
