全垫升气垫船是一种特种的高性能船舶，具有优越的适应性与快速性，由于其特殊的运行方式和使用需求，使得它们的结构形式多样、内部结构层次繁多，目前还没有一套完全成熟的规范和准则来评估气垫船结构强度，且单纯依靠规范计算进行气垫船结构设计亦很难满足其结构强度要求。本文根据全垫升气垫船结构特点，针对其垫升航行和排水航行2种典型运行状态，在对气垫船载荷分量的确定方法及加载方式分析的基础上，通过基于等效设计波法的直接计算法对气垫船总强度校核方法进行研究，为全垫升气垫船总强度评估提供了有效的技术支撑。
Cushion hovercraft is a kind of special high performance ship with excellent adaptability and rapidity. Because of its special operation mode and use demand, its structure forms are various. At present, there is no complete set of mature norms and criteria to evaluate the structural strength of hovercraft. It is also difficult to meet the structural strength requirement of hovercraft structure design by standard calculation. According to the structural characteristics of the cushion hovercraft and the two typical operation states of the hovercraft, lifting sail and draining sail, this paper studies the method of checking the overall strength of the hovercraft by the direct calculation method based on the equivalent design wave method on the basis of the analysis of the method of determining the load component and loading mode of the hovercraft. The overall strength evaluation of hovercraft provides effective technical support.
