全球能源需求不斷增長,海上風能作為清潔可再生能源,日益受到重視。由于近海海上風場已近飽和,海上風能產業正逐步向深水海域邁進。隨著水深增加,固定式風機基礎的施工難度和成本隨之增大,漂浮式海上風力發電機(浮式風機)成為有效的替代方案。浮式風機不僅可用于水深超 60m 的海域,還可靈活調整系泊布局型式,擴大錨固基礎的選址范圍,近年已逐漸用于海上風場建設。
成本是浮式風機面臨的最大挑戰之一。系泊錨固系統(含系泊鏈和錨固基礎)及其相關的勘察、設計和施工費用是浮式風機主要成本之一。為提高系泊錨固效率,共享式系泊錨固方案被提出。共享式系泊錨固方案通常包含系泊鏈和共享式錨固基礎(以下簡稱“共享錨”。傳統獨立式錨固方案中,每臺風機至少通過3個錨固基礎固定,每個錨固基礎僅與單臺風機相連。共享式系泊錨固方案中,單個錨固基礎與多臺風機相連,有效減少了錨固基礎的用量和成本。與獨立式錨固基礎(以下簡稱“單線錨”相比,共享錨的關鍵特征之一是基礎所受荷載來自相連的多臺風機,而傳統的單線錨僅需承受單臺風機的荷載。這導致共享錨的受荷機理更為復雜,多向荷載的耦合作用使得基礎破壞模式更加復雜,基礎承載性能評估更加困難。同時,相同海況及地質條件下,不同系泊布設方式也會影響共享錨的受荷機理及尺寸定型。……
