摘 要:船闸通过能力的计算是合理确定其平面尺度方案的前提。文章基于系统仿真理论构建单级单线船闸仿真模型,模拟船舶进出闸及船闸运行的全过程,计算葛洲坝枢纽船闸扩能工程在闸室平面尺度为280 m×40 m和400 m×40 m、多组过闸船型比例、单向或双向运行方式下的通过能力。主要结论如下:当船宽大于16.3 m的大型船占比分别为50%、60%和60%以上时,船闸通过能力随着22 m宽船舶占比增加而分别呈现增加、先增加后减小、减小的趋势;在相同运行方式和船型比例方案下,闸室平面尺度400 m×40 m方案的通过能力为280 m×40 m方案的1.24~1.32倍;在相同闸室尺度和船型比例方案下,双向运行时的通过能力是单向运行的1.32~1.43倍;葛洲坝枢纽船闸扩能工程能够匹配三峡新通道工程。研究成果为葛洲坝枢纽船闸扩能工程平面尺度确定提供技术支撑。Lock throughput capacity is the condition before deciding lock plane dimension reasonably.A lock simulation model with one level and one lane was constructed,basing on the system simulation theory.The model could simulate the process of ship passing through lock and lock operating.It was used to calculate the lock throughput capacity of the Capacity Expansion Project of Gezhouba Junction,whose plane dimension is 280 m×40 m or 400 m×40 m,and operation mode is one-way or round-way,under the condition of multiple schemes of ship types and percentages.The main results are as follows:Firstly,when over-16.3-meter-breadth ships(i.e.large-scale ships)has a percentage of 50%,60%and more than 60%,with the increase of the percentage of 22-meter-breadth ships,the lock throughput capacity may increase,first increase and then decrease,or decreased.Secondly,with the same operation mode and ship type percentages,the throughput capacity of lock with 400 m×40 m plane dimension is 1.24~1.32 times as large as the one with 280 m×40 m plane dimension.Thirdly,with the same plane dimension and ship type percentages,the throughput capacity of lock in round-way operation mode is 1.32~1.43 times as large as the one in one-way operation mode.Finally,the lock throughput capacity of the Capacity Expansion Project of Gezhouba Junction can match the one of the newly planned lock of the Three Gorges.The achievements can offer technical support to the decision of plane dimension of the Capacity Expansion Project of Gezhouba Junction.
