箱筒型基础结构气浮拖航的稳性计算

Calculation of Stability of Caisson-Cylindrical Foundation Structures Pneumatically Floated during Towage

箱筒型结构是近年来开发成功的一种新型防波堤基础结构。为了探讨这种新型结构在拖航过种中的稳定性问题,进行了典型试验工程,并建立了气浮稳性分析计算方法。结果表明:基础箱筒气浮拖运与拼接上部结构后整体箱筒气浮拖运在技术、工艺、安全上都是可行的,所建立的气浮稳性分析和计算方法是合理的。

Caisson-cylindrical foundation structure is a new type of structure for breakwaters developed successfully in recent years. To explore the stability of this type of new structure during their sea-borne towing, typical experiments were made and a new method was established for the analysis and calculation of the structure when being pneumatically floated. The results indicate that the towage of pneumatically floated caisson-cylindrical structures and the towage of integrated caisson - cylindrical structure with superstructure installed prove to be feasible technically, technologically and safely and that the methods established for the analysis and calculation of the stability of pneumatically floated structures are rational.
