Instrumentation and Modeling of Geosynthetic Load Transfer Platform Performance

The primary objectives of this research are to monitor the short-term (during the construction) and long-term behavior and performance of geosynthetic Load Transfer Platform (LTP) in the state of Louisiana; evaluate and verify (and maybe modify) important design factors and parameters for geosynthetic LTP: load distribution (between piles, geogrid, and soft soil), settlement, and lateral thrust. A design spreadsheet could be developed which will be easy for the engineers to use; conduct finite element parametric study to evaluate the effect of different variables and parameters on the performance of geosynthetic LTP for embankment; and propose design and construction guidance that are needed to establish the department’s design policies and specification.
