摘要
通过对浅海导管架平台桩基冲刷灾害进行定量研究,采用删除弹簧约束及等效桩处理两种方法,运用ANSYS软件的非线性功能,定量评估了桩基冲刷对浅海平台安全度以及对平台极限承载能力的影响,并总结出沿不同角度平台极限承载能力的变化规律,为平台的设计施工和防护提供了可靠依据。
In this article, the disaster assessment for the piling foundation of the jacket platform being scoured in shallow water is carried out through fix ration. Two methods of deleting spring restriction and correcting stake are applied. The influence on safety of offshore platform and its limitation bearing capacity is assessed utilizing non- linear function of ANSYS software The variety rule of limitation bearing capacity is summed up. Trusty foundation for designing and construction of platform is provided..
