Recent Study of Drag Embedment Plate Anchors in China

试验性、理论的研究拖最近在天津执行的埋入板锚大学在这篇研究论文被总结，它包含与学习相关的一系列重要话题拖锚。为测量轨道和运动方向的技术在土壤拖锚，为测量动人的埋入的技术削尖并且逆行链状的形状嵌入拖线，穿入机制和运动学的行为拖锚，最终的埋入深度拖锚，有任意的吸虫节的锚的运动方向，反向的链状的性质嵌入拖线， interactional 性质在之间拖锚和安装现在的工作显著地在设计和分析减少无常拖埋入板抛锚，并且对改进这种新类型的申请有益在近海的设计拖锚。

Experimental and theoretical studies of drag embedment plate anchors recently carried out in Tianjin University are summarized in this research paper, which involve a series of important topics relevant to the study of drag anchors. The techniques for measuring the trajectory and movement direction of drag anchors in soils, the techniques for measuring the moving embedment point and reverse eatenary shape of the embedded drag line, the penetration mechanism and kinematic behavior of drag anchors, the ultimate embedment depth of drag anchors, the movement direction of the anchor with an arbitrary fluke section, the reverse catenary properties of the embedded drag line, the interaetional properties between drag anchor and installation line, the kinematic model of drag anchors in seabed soils, and the analytical method for predicting the anchor trajectory in soils will all be examined. The present work remarkably reduces the uncertainties in design and analysis of drag embedment plate anchors, and is beneficial to improving the application of this new type of drag anchor in offshore engineering.
