Model test research on the floating stability of asymmetric bucket based structure

桶式基础结构形式与其浮游稳定特性密切相关,对称的桶式基础结构形式已应用于工程实践,为丰富桶式基础结构形式,扩大其适用范围,文章研究非对称桶式基础结构浮游稳定性.通过室内水池试验,采用主参数相似制作试验模型,观测模型上部结构在不同位置、不同吃水情况下,整体桶式基础结构的浮游稳定性,归纳出上部结构偏心时,桶式基础结构的吃水深度、封仓水高度、干舷高度以及仓内气压分布形式,进而提出非对称桶式基础结构浮游运输的控制条件,为非对称桶式基础结构设计与施工提供技术支撑.

The bucket based structure form is closely related to its floating stability characteristics.The symmetrical bucket based structure form has been applied to engineering practice.In order to enrich the form of bucket based structure and expand its application scope,the floating stability of asymmetric bucket based structure was studied.Through the laboratory test,using the similar main parameters to make a test model,the floating stability of the overall bucket based structure was observed under different positions and draughts of the model's upper structure,and the draught depth,closed water height,freeboard height and the air pressure distribution in the warehouse were summarized when the upper structure was eccentric,then the control conditions for floating transportation of the asymmetric bucket based structure were proposed,which provides technical support for the design and construction of asymmetric bucket based structure.
