Interactional Properties between Drag Anchor and Installation Line
During penetrating of a drag anchor in seabed soils, complex interaction happens between the anchor and installation line. It is important to clarify the properties of the drag force and drag angle at the shackle of the anchor, which are especially meaningful to the design and theoretical analysis of drag anchors. The interactional properties between the drag anchor and installation line are theoretically and experimentally investigated in the present work. Based on mechanical models for the embedded line and drag anchor, analytical expressions that can predict the drag force at the shackle for both cohesive and noncohesive soils are derived. Theoretical methods are also developed to predict not only the evolution but also the exact value of the drag angle at the shackle during anchor penetration. All the analytical methods are examined by comparing the predicted drag force and drag angle with available experimental data. A detailed parametric analysis is also performed to explore the effects of different parameters on the drag force and drag angle and to determine reasonable values of several key parameters, including the lateral soil pressure factor , the angle of interface friction , and the bearing capacity factor .
