【摘要】：对自升式抛石整平装置暴风自存工况下抗滑移和抗倾覆能力进行了分析.参考CCS《海上移动式平台入级规范》对暴风自存工况的环境载荷进行定义,运用ABAQUS中Subroutine子程序模块来进行环境载荷的施加.根据《移动式平台入级与建造规范》中对自升式平台抗滑移和抗倾覆的要求,对自升式抛石整平装置进行了校核.岩石基床采用基于Mohr-Coulomb屈服准则的理想弹塑性本构模型,位移和转角采用Swipe加载方法.经分析,设计的自升式抛石整平装置满足《规范》抗滑移和抗倾覆要求.
[Abstract]:The anti-slip and anti-overturning ability of the self-storage of the self-storage storm of a self-lifting riprap leveling device is analyzed. With reference to CCS "entry Specification for Offshore Mobile platform", the paper defines the environmental load under the self-storage condition of the storm, and applies the Subroutine subroutine module in ABAQUS to apply the environmental load. According to the requirement of anti-sliding and anti-overturning of self-lifting platform in the Code of entry and Construction of Mobile platform, the self-lifting leveling device is checked. An ideal elastoplastic constitutive model based on Mohr-Coulomb yield criterion is used for rock base bed and Swipe loading method is used for displacement and rotation angle. Through analysis, it is found that the designed self-lift leveling device meets the requirements of anti-slip and anti-overturning.
