10 Chapter 2 OVERVIEW OF CURRENT DESIGN PROCEDURES FOR GEOSYNTHETIC-REINFORCED SOIL STRUCTURES WITH CLOSELYSPACED REINFORCEMENT 2.1 BACKGROUND ON CURRENT DESIGN PROCEDURES The design of geosynthetic-reinforced soil structures involving closely-spaced reinforcements for transportation infrastructure in the US has been conducted using two different approaches: (1) the "GRS-IBS" approach (also identified herein as the "composite design" approach)
