摘要
文章以某一自升式海洋平台桩腿结构作为研究对象,在分析环境载荷作用下自升式海洋平台桩腿—土相互作用机理的基础上,结合通用有限元软件ANSYS,对于如何在有限元建模中正确地考虑桩腿—土的相互作用的问题进行了研究,建立了完整的海洋平台桩腿模型,并分别采用了三种不同的有限元建模方法来模拟土层和桩腿之间的相互作用,通过有限元计算结果与实际检测样本数据的比较,分析了三种简化方法的准确性和可行性。
The main purpose of this study is to develop a correct way to simulate the pile-soil system of thejack-up platform. The characteristics of the interaction between the platform pile legs and pile soil are illustrated. A complete finite element model ofjack-up platform is numerically simulated by general finite element software ANSYS, and adopting three modeling methods to simulate the pile-soil system ofjack-up platform. The accuracy and feasibility of these three modeling methods are discussed by the comparison between the obtained results and the sample data.
