串联板锚内部配置对其嵌入特性的影响研究OA

This study systematically investigates the effects of internal configurations of tandem plate anchors on their embedment behavior through a series of drag embedment tests.Particular emphasis is placed on evaluating how the connection type between the front and rear anchors,the inter-anchor spacing,and the specific types of plate anchors involved(tandem drag-embedment anchors,tandem vertically loaded anchors,and mixed configurations of drag-embedment anchor and vertically loaded anchor(VLA))affect the embedment trajectory and installation bearing capacity.The results indicate that the padeye-to-fluke connection could enhance both embedment depth and installation capacity.An anchor spacing of no less than three times the fluke width effectively mitigated interference effects.Among the tested configurations,the arrangement with a drag embedment anchor as the front anchor and a vertical load anchor as the rear anchor exhibited the best performance,achieving a maximum installation capacity up to 1.3 times the sum of the corresponding single-anchor capacities.This study provides a theoretical reference for the optimal design and engineering application of tandem plate anchors in deep-water mooring systems.
