在对老龄船闸进行扩容时,为了合理地设计闸室尺寸,需要对船闸的通过能力进行评价。通过建立仿真系统来模拟船闸运行状况,并对闸室设计尺寸进行评价,是一种高效节省的方法。对船舶过闸流程进行了详细分析,提出了扩容方案仿真评价系统的基本框架,并建立了船舶交通流、船闸调度和闸室排档等仿真模型。采用快速排闸算法来实现仿真调度,并选取了闸室面积利用率和船舶待闸时间两个指标对仿真结果进行评价。以三堡船闸扩容工程为实例,利用开发的仿真系统,对三堡一线、二线船闸的扩容方案进行了测试和评价。
In the expansion of aged lock, in order to design the lock chamber size reasonably, it is necessary to evaluate the capacity of the lock. It is an efficient and economical method to simulate the operation status of ship lock by establishing a simulation system and evaluate the design dimensions of the lock chamber. A detailed analysis of the ship lockout process is given. The basic framework of the simulation and evaluation system for the expansion plan is put forward, and the simulation models of ship traffic flow, ship lock dispatch and locker stall are established. The fast discharge control algorithm is used to realize the simulation scheduling. Two indicators of the area utilization rate and the waiting time of the ship are selected to evaluate the simulation results. Taking the expansion project of Sanbao ship lock as an example, the developed simulation system is used to test and evaluate the expansion plan of the first and second ship locks.
