Numerical analysis of bucket resistance of new bucket foundation breakwater
摘要
Abstract
The resistance including thefrictional resistance on the bucket wall and the partition wall and the end resistance at the bottom of the bucketis an important factor to maintain the stability of the bucket. Thefrictional resistance on the outside bucket wall is connected with the relative displacement and thecontactstatus between the bucket and the soil. The frictional resistance ontheinside bucket wall and the partition wallrelates with the relative displacement between the bucket and the soil, while the end resistance at the bottom of the bucket is connected with thecontactstatus between the bucket and the soil. Under wave loads, the upper outside bucket wall breaks away from the soil, and the lower bucket wall generate upward displacement against the soil at the sea side, while the bucket wall at the land side is opposite. At the same time, the inside bucket wall and the partition wall generates upward displacement at the sea sideagainst the soil, and the situation is opposite at the land side, while the bottom breaks away from the soil at the sea side and it compresses the soil at the land side.At the head side of the waveswhere an upward displacement is generatedaround the rotating center of the bucket, the frictional resistance on the bucket wall and the partition wall changes fromthepositive frictional resistance under self-weight tothenegativeone, and the end resistance at the bottom of the bucket reduces until to zero. At the same time, at the reverse side of the waveswhere a downward displacement is generatedaround the rotating center of the bucket, the resistance of the bucket increasesbased on its self-weight.关键词
