摘　　要：文章分析了气囊下水的船台的特点,提出了多种气囊下水船台的形式.分别采用静水力和水动力学方法进行了船舶气囊下水的计算,研究了船台形式、气囊布置、船台坡度以及潮位等因素对气囊下水安全性的影响.以两条20000吨级的散货船为例,通过多种方案的比较和系列计算,提出了适宜气囊下水的船台方案.The aspects of the shape of the airbag launching slipway are analyzed in this paper, and many forms are discussed. Both of the methods of hydrostatics and hydrodynamics are used to calculate the airbag launching, to study the effect on the safety of the airbag launching caused by many factors such as the forms of the slipways, the location of airbags, the slope of the slipways and sea level, etc. In the example of two 20,000 DWT bulk cargo, the appropriate forms of the shapes of the airbag launching slipway are brought up by comparison of many methods and series of calculation.
