Study Description

Phases 1 through 3 are complete and Phase 4 is nearing completion. The work performed under this pooled fund study has developed an improved method for internal stability design of MSE retaining walls, the K-Stiffness method. This method appears to produce a more cost-effective design for MSE walls as compared to the AASHTO Simplified Method. The K-Stiffness method has only been developed and validated for high quality sandy backfill soils. The next two phases will extend the K-Stiffness method to 1) marginal quality backfill materials (silts and silty sands) and 2) full-scale field walls that will be monitored for validation. The validation of the K-Stiffness method for marginal quality backfill materials and monitoring full-scale walls is necessary to incorporate this method into the AASHTO LRFD design specifications.

Objectives

Phase 5 will 1) construct and test two full-scale walls with non-select fill, 2) update the report on the physical testing of walls 1 through 11 (tested in phases 1 through 4) based on the experience with the instrumented SR 18 walls in Washington state, and 3) update the numerical modeling of walls 1 through 11 and carry out a parametric analyses.

Phase 6 will 1) construct and test one full-scale wall with non-select fill, 2) perform data reduction, interpretation, numerical modeling, parametric analysis, and report on the physical testing of the two walls constructed in Phase 5, 3) perform data reduction, interpretation, numerical modeling, parametric analysis, and report on the physical testing of the wall constructed in Phase 6, 4) investigate the effect of material type on in-soil stiffness, 5) update the K-Stiffness method based on results from the walls constructed in Phases 5 and 6 and to include seismic design, and 6) produce a final report on Phases 1 through 6. (updated June 2005)

Comments

Phase 5 is scheduled to begin in the summer of 2005 and continue through late 2006. Phase 6 will begin in late 2006 and is planned to finish in December of 2008. Additional funds are currently being solicited to complete the work.
