| 摘 要： | 综合考虑风浪流等环境载荷、桩靴与土壤之间的相互作用行为及静水压力和波浪动压力所引起的浮力效应的影响,运用有限元软件模拟了自升式钻井平台的动态响应过程,获得了0°环境载荷作用下自升式钻井平台的船体位移、桩腿危险处应力、桩靴载荷的变化规律。研究结果表明:自升式钻井平台的动态响应周期约为38s,是波浪周期的2.8倍,且在环境载荷作用角度为30°时,船体位移峰值最大,而位移均值在45°时最大。

| Abstract: | Considering environmental load, spudcan-soil interactions, influences of hydrostatic and wave dynamic pressure, Dynamic response of Jack-up platform was simulated using the FEA software. The variation of the hull displacement, maximum leg stress and loads on spudcans under 0° environmental loads were obtained. The results show that: The dynamic response period was about 38s, which was 2.8 times of the wave period. The maximum hull peak displacement appeared under 30° environment loads, while the maximum average value appeared at 45°. |

| Keywords: | jack-up dynamic response environmental load spudcan and soil coupling model load direction |
