Calculation and Analysis of Caisson Floating Stability for Some Port

Through solid observation of caisson floating situation in some port,some problems are discussed,which should be taken into consideration before selecting the related parameters in the process of calculating caisson floating stability by criteria.Meanwhile,caisson floating stability is checked.By analyzing mechanics characteristics of floating caisson structures,it is discussed the caisson floating stability being impacted by water flowing among cabins as well as the movement rule of buoyant centre against caisson.Then it is put forward that the grade of caisson stability can be measured by anti-overturning moment,the calculation method and caisson-filling-with-water mode based on water-fill leveling method.The reliability of above mentioned analysis is verified by some port project,which will provide the reference for the similar projects.
