摘要
作为深海工程应用中一种新型的拖曳嵌入式系泊基础,法向承力锚与目前新型的深水绷紧索系泊方式结合,在深水条件下的优势非常明显。综合比较了新型拖曳锚、吸力锚以及桩锚在施工、性能以及经济性等多方面的特点,提出了开展新型拖曳锚研发的若干关键技术。在对国外的实验研究现状进行综合评述的基础上,重点介绍了在构建新型拖曳锚模型实验平台方面取得的成果,涉及模型水槽、拖曳与回收系统、测量系统、模型锚板设计以及拖曳-系泊转换机构等关键技术。
Being a new-type moonng foundation used for deepwater engineering, which is embedded in seabed soils by dragging, the vertically loaded anchor (VLA), combined with the taut-wire mooring system, has predominant advantages in deepwater applications compared with other types of anchors. In this paper, systematical comp^trisons in installation, working performance and economy are summarized among the new- type drag anchor, suction anchor and anchor pile. Key techniques in research and development of new-type drag anchors are then proposed. Based on the review of experimental study on drag anchors, the research achievements aiming at designing and constructing a model platform for research of new-type drag anchors are briefly described, which involve several key techniques in model experiments, including the model flume, drag and retrieval system, measurement system, design of model anchor and switch machine from dragging to mooring.
