摘要
伞式吸力锚作为一种新型海上风电基础,现已在数值模拟方面进行了大量的研究,但缺少相应的室内试验。本文对伞式吸力锚(USAF)水平静力承载特性和波致土体液化中伞式吸力锚承载特性进行了室内模型试验,并与无锚枝吸力锚(SAF)进行了对比试验。研究发现,USAF的锚枝使得锚体转动中心升高,锚体承载性能得到提升;在波致液化海床土中,USAF的承载性能优于SAF,并且具有一定的防冲刷效果。
Umbrella suction anchor as a new type of offshore wind power foundation,has been in the numerical simulation of a lot of research,but the lack of the corresponding indoor test.In this paper,the horizontal load characteristics of umbrella suction anchor(USAF)and the characteristics of umbrella suction anchorage in wave liquefaction were studied in laboratory and compared with those without anchorage anchor(SAF).It is found that the anchor of the USAF increases the rotation center of the anchor body and the bearing capacity of the anchor body is improved.The carrier performance of USAF is better than that of SAF in the wave liquefied seabed soil and has a certain anti-scouring effect.
