摘要：According to the urgently application of catenary mooring system in the project of South China Sea, drag embedment anchor which could resist large horizontal loads is the most reasonable type of anchor foundation. Therefore the ultimate pullout bearing capacity analysis is one of the key issues in the design of offshore structures. The undrained seabed soft clay and drag embedment anchor is respectively simulated by ideal elastic-plastic model and rigid model. Considering the contact friction between the drag embedment anchor and seabed clay, the two-dimensional finite element calculation model is established. The influence laws of embedment depth, angle between shank and fluke, mooring force angle to the ultimate static pullout bearing capacity of drag embedment anchor are respectively studied under monotonic loading. The specific numerical results and analysis conclusions would be helpful in engineering practices. ? 2012 ejge.
