摘　　要：采用系统仿真模型模拟分析研究内河船闸通过能力是一种合理、准确的方法,船闸通过能力仿真研究的各参数中船舶进出闸速度、启动间隔时间具有随机性。通过构建船闸通过能力系统仿真模型,研究模型中上述随机参数取平均值的合理性。通过仿真模拟试验表明,随着船舶进出闸速度取值随机性增强,船闸通过能力逐渐减小,但这一减小幅度在工程设计中可以忽略;而启动间隔的取值随机性对船闸通过能力没有明显影响。因此,采用系统仿真方法确定船闸通过能力时模型参数取平均值是合理的,且综合考虑各因素影响建议在建模时各参数取平均值。It is a reasonable and accurate method to use system simulation analysis to study the capacity of inland locks.Among the parameters of lock capacity simulation,ship entry and exit speed and start interval time are random.The rationality of taking the average value of these random parameters for the model was studied by constructing the system simulation model of lock capacity.The simulation test shows that with the increase of randomness of ship entry and exit speed,the lock capacity gradually decreases.However,this decrease can be ignored in engineering design.The randomness of the start interval time has no significant effect on lock capacity.Therefore,it is reasonable to take the average value of model parameters when using the system simulation method to determine the lock capacity.Considering the influence of various factors,it is suggested to take the average value of the parameters in the modeling.
