Experimental and Shape-Optimization Research for Drag Anchors

Drag anchor is a new type of mooring foundations, and there are still many key technical problems which need to be further understood and resolved. The general situation of experimental studies for drag anchors, and also the advantages and disadvantages of kinds of experimental methods are summarized. Based on the present study, it is pointed out that the researches for dragging and positioning techniques, the methods for measuring multi-parameters and kinematic trajectory and the approaches for improving the repeatability and precision are essential for the experimental studies and need to be investigated deeply. According to the evolution of anchor-shape design, the functional features and shape-optimization principles for the seven structural components of a drag anchor are proposed. It is suggested that good embedment performance and efficiency, favourable processability, stability and bearing performance are the targets to be achieved in the shape design of drag anchors.
