摘要

通过建立复杂海洋荷载作用下单桩式海上风力机三维有限元模型来考虑冲刷效应对风力机结构动力响应的影响

同时考虑冲刷效应所导致的土体力学性能变化影响

并比较整体冲刷和局部冲刷对海上风力机动力响应的不同影响

结果表明不同冲刷形式在不同荷载条件下对风力机结构响应的影响不同。单独地震作用下的局部冲刷风力机结构响应大于整体冲刷。然而

单独风浪流荷载和风浪流-地震联合作用下

冲刷深度较大时

风力机结构除弯矩外的响应出现整体冲刷大于局部冲刷的现象

表明在复杂海洋荷载作用下需考虑冲刷效应对单桩式海上风力机动力响应的影响

且不同冲刷形式对海上风力机动力响应的影响不同。

Abstract

In this paper

the influence of scour effects is considered by establishing a three-dimensional finite element model under wind-waves-current loads and seismic action

and the different influences of global scour and local scour on the dynamic response of the MOWT are compared. The results show that different forms of scour have different responses of the MOWTs under different loading conditions. The response of the MOWT system to local scour under seismic action is greater than that to global scour. However

with the exception of the bending moment

the response of the wind turbine system is observed to be greater under global scour than under local scour for larger scour depths under wind-waves-current loads and combined wind-waves-current loads and seismic action. This suggests that scour effects must be considered on the dynamic response of MOWTs under a complex marine environment. Furthermore

it can be observed that different forms of scour effects exert varying effects on the dynamic response of MOWTs.
