Model Tests on The Bearing Capacity of Modified Suction Caisson under Inclined Pullout Loading
In this paper, a model test was conducted to investigate the bearing characteristics of the skirt suction foundation under an inclined load. Through changing the skirt width, skirt height, loading angle and loading speed, the change of bearing capacity of the modified suction caisson base under an inclined load was explored, and the negative pressure in the main barrel and the negative pressure in the modified suction caisson were analyzed. The results show that the bearing capacity of the modified suction caisson base under the effect of inclined load increases with the increase of the skirt width, skirt height and loading speed, and the corresponding base displacement value increases when the ultimate bearing capacity is reached. With the increase of the load angle, the negative pressure in the barrel increases although the basic bearing capacity decreases.
