Abstract
Strains induced in a geosynthetics liner sheet that was installed in the slope of a controlled coastal disposal site were measured in the construction stage of filling the protective soil layer. Also, laboratory tensile tests and the corresponding FEM were conducted to obtain the relationships between the measured values by means of strain gauges and the actually induced strains in the liner sheet since the former becomes smaller than the latter that is made of very flexible materials. It was observed that the strains were induced both in the downward and horizontal directions due to the shear forces by the self weight of the protective soil and the deformation caused by the uneven surface on which the liner sheet was placed under the sea level.
