| 摘 要： | 以某122 m自升式钻井平台为分析对象,建立其有限元模型,包括材料非线性、几何非线性以及桩土非线性相互作用,在风浪流作用下,基于三维约束New Wave理论对自升式钻井平台的动态响应进行分析,研究海洋波浪方向传播特性和随机特性对平台动力响应的影响。在建立模型中实现风暴工况下水面高程和水粒子运动的描述,响应结果按甲板位移进行对比。结果表明,相比其它波浪理论,三维约束New Wave理论在平台动力响应分析中体现了一定的优越性,不仅能较准确地反映波浪的真实特性,而且能确保结构性能评估的安全性和合理性。

| Abstract: | Taking a 122 m jack-up drilling platform as an analysis object, the corresponding finite element model is established, considering material nonlinearity, geometric nonlinearity and pile-soil nonlinear interaction. Under the action of wind, wave and current, the dynamic response of the jack-up drilling platform is analyzed based on the three-dimensional constrained NewWave theory, and the directional propagation of ocean wave is studied. Besides, the influence of wave direction propagation characteristics and random characteristics on the dynamic response of the platform is discussed. In the model, the water surface elevation and the movement of water particles are described under storm condition, and the response results are compared according to the deck displacement. The results show that compared with other wave theories, the three-dimensional constrained NewWave theory has some advantages in the dynamic response analysis of the platform, which can not only accurately reflect the real characteristics of waves, but also ensure the safety and rationality of structural performance evaluation. |
