摘要
为获得复杂海洋环境下海洋平台受海啸荷载作用的实际情况,本文提出一种计算海啸荷载的方法,即海啸理论。同时利用ADINA软件建立导管架海洋平台有限元模型,并将所计算出的海啸荷载施加到平台上进行受力分析。数值仿真表明:海洋平台在海啸荷载作用下的位移集中在上部支撑和甲板上,甲板上的应力变化主要由水平的海啸荷载和重力共同作用产生,且经过对比可知海啸荷载理论是比较正确的,更加符合实际情况。
In oeder to get the loading situation one tsunami loading calculation method is proposed of offshore platform in complex ocean environment, in this paper： tsunami theory. At the same time the finite element model of jacket offshore platform was established based on adina software and would impose to the load calculated on the platform to make stress analysis. Numerical simulation shows that the displacement of platform under the wave load focused on the upper support and deck, main deck stress is generated by the tsunami loading and the level of gravity interaction more fit with the actual situation.
