摘　　要：为有效保证船用气囊下水过程安全可控,气囊下水技术的理论研究正在进行。文章总结当前在囊体的复合材料特性、非线性接触下承载能力、下水动态过程分析和气囊与船体结构耦合作用等气囊下水技术方面的研究成果,提出尚待解决的下滑过程稳定性、气囊抗冲击和爆破力学模型等方面的问题,并指出下一步的研究方向和可能的研究路线。同时,分析气囊在大桥护栏、海上围栏和浮式防波堤等方面的应用前景,为提高气囊下水的可靠性,并将其推广到类似海上充气结构中提供参考。In order to guarantee the safe and controllable launching process of ship airbag, theoretical researches are still progressing. Recent research achievements on ship airbag launching are concluded, such as composite material property of airbags’ membrane, bearing forces with nonlinear contact, analysis of dynamic launching process and the coupling effect between airbags and the ship structures. The further study directions are provided on stability during sliding, impact resistance capability and blast mechanical model etc. with possible technical routes. At the meantime it also predict the application visions for the airbags used as bridge defenses, floating defends and floating breakwaters. It tends to provide references for increasing reliability for ship launching with airbags and extends the application to similar marine pneumatic structures.
