摘　　要：本文给出了根据船模系列浅水试验结果回归而得的高速圆舭艇浅水阻力计算公式．对亚临界速度区和超临界速度区分别采用不同的公式修正浅水对阻力的影响．文中给出了区分上述速度区域的临界速度计算公式，适用于Fr＜0．8的高速圆舭艇．为检验本文公式的计算精度，用两艘实艇浅水试验结果进行核核．结果表明，公式的精度足以满足工程使用要求．A method for evaluating the resistance of high speed round bilge hulls in shallow water is presented, based on model test series and regression analysis. The shallow water resistance calculation formulas given in this paper are expressed for sub-critical and super-critical speed regions, and a formula for discriminating sub-or super-critical speed is given.These formulas may be used for speeds up to Fr =0.8. In order to examine their accuracy,two full scale crafts trials were conducted. A comparison between the test data and calculated results shows that the agreement is satisfactory. Furthermore, estimation charts are made for practical use.
