Study Description

FHWA Contract: DTFH61-03-P-00312

Objectives

Develop design guidelines for geosynthetic reinforced soil-pile supported embankments. The primary objective of this investigation improve the design of pile supported embankments with the use of geosynthetic reinforcement to distribute the embankment loads onto the piles and to limit the punching of piles into the embankment during the consolidation of the foundation soil.

Scope of Work

Used numerical methods to simulate the behavior of GRS-pile supported embankments. Parametric studies will be performed by a Finite Element (FE) method to simulate embankment behavior for a variety of ground conditions. The FE model will include simulations for linear and non-linear soil conditions.

Comments

The draft final report has been submitted by the Collin Group. During the week of August 8th , 2005, the report will be distributed to a geotechnical staff member in each of the states participating in this TPF study. The report is also being reviewed by FHWA to determine whether to print the document as an official FHWA research report.

Update: 12/8/09: Final report is not available for posting, as it was not officially printed.

Note: A related report prepared by Virginia Tech discusses alternate views of GRS-pile technology. The title of this report is; Design of Bridging Layers in Geosynthetic - Reinforced, Column-Supported Embankments by George M. Filz and Miriam E. Smith, Virginia Polytechnic Institute & State University, July 2005.

Subjects: Soils, Geology, and Foundations
