经过数据分析，揭示了罐壁应力变化、分布与传递的内在规律，为确保今后油罐举升方案的制定和安全实施提供了科学依据。
Based on the data analysis results, the laws of the stress change, distribution and transfer are primarily revealed, which can provide a scientific fundament for tank lifting in scenario and safety.
结果显示：扣带沟缘支和外侧沟后升支是识别中央沟的标志，若出现壁间回则更易识别中央沟；
The results showed that marginal ramus of cingulate sulcus and posterior ascending ramus of lateral sulcus are the landmarks for recognition of central sulcus.
现场实验证明，单点提升力和罐壁受力点的应力状况直接关系到油罐举升的安全。
In the field tests, it has been proved that the safety of oil tank lifting is closely correlative with the lifting force and the stress status at the action point.
在自升式平台的主船体中这种结构更是大面积的得到应用，其主甲板、舱壁、机械甲板和底板等都是板梁组合结构。
Especially, there are many stiffened plates in the hull of jack-up platform, for example the main deck, bulkhead, tank top and bottom plating.
