In harbor facilities such as caisson type seawalls and quays, the geotextile sheet laid between the backfill stone and the sand is often damaged by the time the landfill is completed, which is a factor in sand leakage into backfill stones. The main causes of damage are as follows. 1) When it flutters or swings due to waves or wind, it comes into contact with the backfill stone and wears. 2) Abnormal tension is generated by being drawn in by the sinking of the geotextile sheet after it floats due to waves or tides. 3) Abnormal tension is generated because the geotextile sheet is pulled in by throwing in landfill sand.
Therefore in this study, we conducted elemental tests and load confirmation and demonstration experiments of the "geotextile sheet pull-in reduction method", which is a measure against pull-in using auxiliary materials, and clarified the pull-in suppression effect.
