摘　　要：为了研究内河限制性航道中船舶航行下沉量,建立了室内概化物理模型,开展试验研究。模拟测试了1000~3000 t级船舶在不同渠道宽度、水深及航速条件下船舶航行的下沉量,分析了影响下沉量的主要因素,比较了实测下沉量与常用经验公式计算值的误差及相关系数,提出了以船舶方形系数、航速、阻塞比为变量的下沉量计算改进公式,并进行了验证。研究结果表明,所提改进公式可用于内河限制性航道的水深计算及航道断面设计。In order to study the subsidence of ship in restricted inland waterway,an indoor generalized physical model was established and relevant research was carried out.In this paper the sinkage of 1000-3000 t ships under different channel widths,water depth and speed were tested.The main factors affecting the subsidence were analyzed.The error and correlation coefficient between measured subsidence and estimated value of several common empirical formulas were compared.An improved formula for calculating the subsidence with the variables of ship square coefficient,speed and blocking ratiowas put forward and verified by the measured values.The results show that the improved formula can be used to calculate the depth of restricted channel and design the channel section.
