摘要
针对隧道施工过程中各作业线内部产生的机械排队作业现象,采用随机过程排队论方法以Ⅲ级围岩为例研究中硬围岩长大隧道施工循环作业线中机械配套问题,提出顾客为有限源的M/M/1/m/m排队系统的求解方法,由此得到基于快速施工的最优机械配套方案。结合黄岩隧道妹子娘冲斜井段的工程实例,得到Ⅲ级围岩下出碴运输系统以及锚喷支护系统的最优配置,可为工程实际施工提供一定参考。
Aimed at the mechanical queuing phenomenon produced within the each working line of tunnel during long tunnel construction, and the problem of mechanical matching in the loop operation line was studied based on the queuing theory of the stochastic process theory by taking grade III wall rock as a example. A method for solving the M/M/1/m/m queuing system with limited sources was proposed. Then, the optimal mechanical matching scheme based on rapid construction was obtained. Finally, combined with the engineering example of the Huangyan tunnel, the optimum configuration of the mucking and transporting system and the bolting and shotcrete supporting system under grade III wall rock was obtained, and it can provide some reference for the actual construction of the project.
