Experimental research on development of low skirted friction suction caissons and its penetrability
In this study,a low skirted friction type suction caisson model was proposed to optimize suction foundation,reduce soil plugging effect,and improve penetrability and load capacity. Indoor model tests were conducted to investigate the relationship between penetration force,resistance and volume in negative pressure (P)-sinker volume (y) curves with different suction caisson types. Furthermore,the study analyzed differences among various caisson models and confirmed their penetrability and sinker volume. Results demonstrate that the low-skirt friction type suction caisson,offering improved penetrability,effectively mitigates soil plugging and improves caisson bearing capacity.
