Figure 4.31 The elastic deformation versus the number of loading cycles for the 15 cm thick
geocell-reinforced RAP base section
Figure 4.32 shows the measured maximum strains on the geocell wall at different
locations during the cyclic plate load test. The symbols, orientations, and locations of strain
gauges affixed on geocell wall are shown in figure 4.3. The maximum strains were recorded
manually during the test. It is shown that the tensile strains developed at all of the top gauges
while the compressive strains occurred at the middle gauges. The strains at the bottom gauge of
the central geocell and top gauge of the third geocell were not measured because the gauges
broke during the construction of the base layer.
