中文摘要：

推进船型标准化是提高三峡船闸实际通过能力的有效途径之一。为定量研究船型标准化程度对船闸实际通过能力的提升效果，在研究三峡库区船舶过闸流程的基础上采用系统仿真方法构建三峡库区船舶过闸仿真模型．模拟不同船型标准化率下三峡船闸的实际通过能力。仿真试验结果表明：仿真模型可以真实地反映三峡库区船舶过闸情况：船型标准化率达到90％以上时，标准船型对提升船闸运行效率的优势凸显。相比于对船闸实际通过能力的提升，船型标准化率的提高对船舶过闸服务质量的改善更为显著。

英文摘要：

Ship-type standardization is an effective way to improve the traffic capacity of the Three Gorges ship lock.This paper studies the quantitative effect of standard ship rate on traffic capacity of ship lock.The paper sets up a simulation model to study the traffic capacity in different standard ship rates based on the process of ships passing through the Three Gorges ship lock.The simulation results show that the simulation model can well simulate the process of ships passing through the Three Gorges ship lock, and the benefit of standard ships in prompting the efficiency of the ship lock will multiply when the standard ship rate is more than 90%. Compared with the traffic capacity of the ship lock, the increase of the standard ship rate can improve the quality of ship service remarkably.
