Abstract: The key analysis of the stability of the new bucket foundation breakwater on soft foundation is the analysis of the soil pressure on the bucket wall. According to the practical works and by means of numerical analysis, the soil pressure distribution on the bucket wall is analyzed for different load levels, different heights of load application points and different soils in this study. By analyzing, it is found that in different conditions the soil pressure on the bucket wall can be divided into the active region on the circle end of the sea side, the static region on the straight side and the passive region on the circle end of the land side for the new bucket foundation breakwater on soft ground. Comparing with the theoretical Rankine active earth pressure, passive earth pressure and static earth pressure, on sea side, the earth pressure in the active region ranges from active earth pressure to static earth pressure, while on the land side, the earth pressure in the passive region ranges from static earth pressure to passive earth pressure. On the straight wall of the two flanks of the bucket, the earth pressure is approximate to the static earth pressure. For the new bucket foundation breakwater on soft foundation, on the two circle ends of the bucket, the distribution of the soil pressure is stepped linearly along the depth direction, and the relationship is linear between the per breadth resultant of soil pressure and load levels, and when the height of load application points changes, the law of the distribution of the soil pressure is similar. According to the distribution patterns of the earth pressure on the bucket wall, a simplified calculation method is given in this study, and the analysis of the stability of the bucket will become more convenient.
