Performance Tests for Geosynthetic Reinforced Soil (GRS)

Project Information

Project ID:
FHWA-PROJ-11-0061
Project Abstract:

A performance test is a load test on a geosynthetic reinforced soil column. A resulting stress-strain (or load-settlement) curve describes the stiffness and capacity of that composite. Different factors that affect performance (e.g., reinforcement material, reinforcement strength, reinforcement spacing, backfill type) will be investigated.

Goals

The primary objectives of this research report are to:

(1) Build a database of Geosynthetic Reinforced Soil (GRS) material properties that can be used by designers or for Load and Resistance Factor Design (LRFD) calibration.

(2) Evaluate the relationship between reinforcement strength and spacing.

(3) Quantify the contribution of the frictionally connected facing elements at the service limit and strength limit states.

(4) Assess the new internal stability design method proposed by Adams et al. 2011a for GRS.

(5) Perform a reliability analysis of the proposed soil-geosynthetic capacity equation for LRFD.
