摘要

气浮特性是筒型基础的主要特性之一,针对筒型基础在气浮过程中系泊机理不明的问题,该文通过模型试验对四角筒型基础作为漂浮式风力机基础在张紧式系泊状态下的运动特性进行研究,分析吃水深度、水深、锚固距离对多筒型基础运动响应的变化规律。得到如下结论：结构在小周期下呈现波频运动,大周期下呈慢漂运动特性;吃水深度的增加、纵荡运动呈现与垂荡运动和纵摇运动相反的变化趋势;浅水效应使得较浅水深下结构的摇荡运动大于较深水深;锚固距离的增加可一定程度上改善慢漂运动对纵荡的影响,但却增大了结构的垂荡和纵摇运动。

Abstract

The air flotation characteristics are a key aspect of bucket foundations. However, the mooring mechanism for this type of foundation during air-floating is not well understood. In this paper, model tests were conducted to analyze the taut mooring characteristics of a four-bucket foundation as a floating wind turbine foundation. The effects of draft depth, water depth, and anchorage distance on the motion response of the model were investigated. Our findings are as follows： the structure exhibits wave frequency motion in short periods and slow drift motion in large periods. As the draft increases, the heave motion shows an opposite trend to surge and pitch motion. The shallow water effect causes greater heave motion in shallow depths compared to deeper depths. Increasing the anchorage distance can mitigate the impact of slow drift on surge motion, but it increases the heave and pitch motion of the structure.
