| 摘 要： | 在船闸引航道流场的数模计算中,得到停泊段的流速和比降,用《航道整治水力计算》1]中船舶航行阻力公式,计算停泊段船舶的系缆力,该力与实测值、规范公式及规范简化公式计算结果作比较,认为仅适用于断面系数n≥12的情况,而不适合断面系数n<12船舶系缆力计算。

| Abstract: | The velocity and gradient in the mooring section of lock approach are obtained from numericd simulation of the flow field.It's considered that when the ship resistance formula in "Hydraulic calculation for channel regulation" is used to calculate the ship mooring force,it only applies to the case of sectional factor n≥12 and does not applies to n<12,as compared with the measared values and the calculated ones from standard and simplified formulas. |
