为了解决隧道出渣过程中主要施工机械即装载机、出渣车优选的问题,采用闭合排队网络模型,模拟装渣系统1和卸渣系统2的运转过程,分别计算在不同机械配置下各系统的目标参数及生产效率,并优化机械配置。工程实例表明,对于选定的同数量机械,随着型号的不同,出渣所用时间有所变化,但变幅不大;对于选定的同型号机械,刚开始随着出渣车数量的增加,出渣所用时间明显减小,当出渣车增加到一定数量时,出渣所用时间变幅明显变小。
In order to solve the optimization problem of the main construction machinery, ie loader and slag car, in the process of tunneling, the closed queuing network model is adopted to simulate the running process of the slag loading system 1 and the slag removing system 2, The target parameters and production efficiency, and optimize the mechanical configuration. Engineering examples show that, with the same number of selected machinery, with the different models, the time spent tapping has changed, but the range is not large; for the same type of machinery selected, the beginning with the increase in the number of slag cars , The time spent in the slag was significantly reduced, when the slag car increased to a certain amount, the time spent changing the slag significantly smaller.
