Extended Veletsos-Younan Model for Geofoam Compressible Inclusions behind Rigid, Non-Yielding Earth-Retaining Structures
Geofoam is a type of cellular geosynthetic that can be used to reduce lateral earth pressures acting on rigid earth-retaining structures (RERSs) under a variety of soil and load conditions. One of the geosynthetically-functional ways in which geofoams do this is as a compressible inclusion to allow shear-strength mobilization of retained soil through controlled yielding which involves the well-known soil mechanics mechanism of arching. This paper describes how a mathematical model developed by Veletsos and Younan for a seismic-load application not involving geofoam was modified and extended to create a novel solution involving the use of geofoam as a compressible inclusion. An illustration of how this Extended Veletsos-Younan model can be applied in practice is also included using a case-history and full-scale, 1-g physical tests.
