自施工式桶形基础平台着底稳性研究

On supporting stability of bucket foundation platform with self-construction

自施工桶形基础平台在海上受风、浪、流、冰等载荷作用,平台应有足够的着底稳性,以保证平台的作业安全。根据研究对象和环境参数,确定了工作水深17 m的典型自施工式桶基平台主体结构形式,阐述了平台的抗滑稳性、垂向稳性和抗倾稳性计算方法,计算结果表明平台具有良好的着底稳性,平台在着底状态是安全的。

Due to the loads of wind,wave,current,ice and so on,the bucket foundation platform with self-construction should have sufficient supporting stability on ocean bottom for the safety operations to the platform.According to the research object and the environment parameters,it is determined that the structure type of the self-construction bucket foundation platform that has the operation ability in 17 m of water.The calculation methods are discussed,including the anti-sliding stability,anti-overturning stability and vertical stability.The calculation results show that the platform has sufficient supporting stability and is safety when sitting on ocean bottom.
