摘要
文章以大连庄河临近的渤海海域为例,基于SACS模型研究大直径单桩基础结构在渤海海冰环境下的抗冰性能。研究结果表明:在静冰力方面,根据不同规范推荐公式设计的大直径单桩基础材料的用量可相差约10%;在动冰力方面,在不同冰速和冰厚的组合工况下,低冰速和大冰厚作用下的大直径单桩基础结构更易产生持续振动。
This paper took the Bohai Sea area nearby Dalian Zhuanghe as an example,to study the reactions to ice loads of single large-diameter pile foundation of offshore wind turbine based on the SACS model.In terms of static ice force,the recommended formulas of different codes were compared,and it was found that according to different codes,it could lead to about 10%difference in the amount of large-diameter single pile foundation materials.In terms of dynamic ice force,different ice speeds and ice thicknesses combinations were analyzed.The ice vibration response of the large-diameter single-pile foundation structure indicated that the structure was more likely to generate continuous vibration under the action of combinations of low ice speeds and large ice thicknesses.
