摘要：
The vertical bearing capacity of the suction anchors is closely related to the loading rate. The loading rate is a critical parameter. In this study, ABAQUS was used to perform a numerical analysis of the behavior of suction anchors under partially drained conditions, considering the passive suction generated by the soil, which is the main feature during the uplift process of suction anchors. The results indicated that the suction anchor gradually moved from the drained condition to the undrained condition with an increase in the normalized rate V. When 0.1<V<47, it is partially drained, and the uplift force and negative pressure inside the anchor are more sensitive to the loading rate at this stage.
