Abstract

Abstract

The response of suction anchors subjected to inclined uplift loading in sand foundation is not clear. The bearing properties of suction anchors in sand foundation was studied through a series of model tests. Five suction anchor models with the aspect ratio of 0.5， 0.8， 1.0， 1.5 and 2.0 were prepared to explore the effects of loading positions and load inclination angles on their bearing characteristics. The test results show that suction anchors with various aspect ratios might produce instability mechanisms such as forward rotation failure， backward rotation failure and sliding failure when the load inclination angle was less than 60°. The pull-out capacity of suction anchors decreased with the increase of load inclination angle. For suction anchors with an aspect ratio less than 1， the optimal anchoring point is located at the middle point of the skirt wall， while for suction anchors with an aspect ratio greater than 1， the optimal anchoring point moved down to about 70% of the buried depth of the skirt wall.
