Variation of Lateral Soil Resistance Due to Two-Way Cyclic Loading

초록

In this study, the variation of lateral soil resistance of the monopile were investigated through centrifuge tests. The soil used in the experiment was Jumunjin standard sand, and the soil deposit was created with a relative density of 80%. The static load test was carried out to obtain the static lateral capacity, and the magnitudes of cyclic load were determined at 30, 50, 80 and 120% of the static capacity. A hundred cycles were applied to the pile head with a frequency of 0.125 Hz. The lateral soil resistance and pile displacement of the monopile subjected to cyclic loading were calculated through experimental data. At 2 and 5 m depth, the soil resistance increased with increasing number of cyclic loading, while the resistance decreased at 7 and 9 m depth. © 2019, Springer International Publishing AG, part of Springer Nature.
