摘 要:为进一步了解船舶在通航隧洞中航行阻力的变化规律,针对大型船舶提出航行阻力估算公式,建立物理模型开展船模试验对公式进行验证与分析。结果表明:阻力实测值与公式拟合程度较高,验证效果良好;隧洞水域横截面积的变化对航行阻力扰动更大,航行阻力对隧洞水域横截面积的敏感性高于航速;航行阻力与航速的二次方成正比,随着通航断面系数的增大而减小。In order to further clarify the changing law of the sailing resistance of a ship in a navigable tunnel,this paper proposes a sailing resistance estimation formula for large ships and builds a physical model to carry out ship model tests to verify and analyze the formula.The results show that the measured resistance value and the formula have a high degree of fitting,and the verification effect is great.The change of the cross-sectional area of the tunnel water area has a greater disturbance to the sailing resistance,and the sensitivity of the sailing resistance to the cross-sectional area of the tunnel water area is higher than that to the ship speed.The sailing resistance is proportional to the square of the ship speed and decreases with the increase in the navigable section coefficient.
