Model Shaking Table Test of Geotextile Reinforced Embankments on Inclined Ground and Its Stability Analysis

概要

A series of model shaking table tests and their stability analyses were performed with an aim at estimating the earthquake resistance of geotextile reinforced embankments.Test results showed that the earthquake resistance increases when geotextiles are thickly included, geotextiles with large stiffness are used, and a slope surface is rolled up with geotextiles.A few variations of stability analysis formulae were briefly reviewed. The simplest analysis assuming a given constant elongation of geotextiles showed a fairly good agreement with experimental results. Another stability analysis which pursues a consistent strain of soil and geotextile was also conducted and compared with experimental results, which gave a fairly larger strain of geotextiles in case of non-woven fabric.
