摘要
以某自升式平台为例,介绍海上自升式平台底座结构强度分析的过程及方法,通过原理分析和算例实现,从静载工况、横摇及升沉工况、纵摇及升沉工况和底座梁特性4个方面计算危险简支梁的受力分布,阐述拖航工况下主机底座结构强度分析的一般原理。
The offshore self-elevating units have the characteristics of big weight and complex load, so the requirements of structural strength for the unit＇s foundation are strict. To illustrate the process and methods of strength analysis of the heavy equip- ment foundation, an offshore self-elevating platform is taken as example to calculate the stress distribution for the most dangerous simply supported beam theoretically under various load conditions. The general principle of main engine foundation structural strength analysis under the transit condition is set forth.
