随着我国海洋石油的开发,海洋石油平台的设计和建造,已经是提到日程的一个重要课题。钢筋混凝土重力式平台具有多功能(钻井、采油、储油等)、自持能力高以及建造技术容易、节省钢材、成本低廉的优点,近十年来这种平台在欧洲北海有了突破性的发展,成了除钢质导管架平台以外的世界上主要的石油钻、采平台。钢筋混凝土重力式平台主要是由甲板、腿柱以及储油罐体所组成,其中腿柱及储油罐体是用不同形状的钢筋混凝土壳体构成。由于体型变化多样,结构复杂,所以给平台结构的静力分析带来许多困难。
With the development of China’s offshore oil, the design and construction of offshore oil platforms has been an important topic on the agenda. The reinforced concrete gravity platform has the advantages of multi-function (drilling, oil recovery, oil storage, etc.), high self-sustaining ability, easy construction technology, saving steel, and low cost. In the past decade, this platform has made a breakthrough development in the North Sea of Europe. It has become the world’s major oil drilling and mining platform in addition to the steel jacket platform. The reinforced concrete gravity platform is mainly composed of a deck, legs, and an oil storage tank body, wherein the leg columns and the oil storage tank body are composed of reinforced concrete shells of different shapes. Due to the variety of body types and complex structures, it has brought many difficulties to the static analysis of the platform structure.
