再生工程机械化施工系统的运行规律

以沥青混凝土路面再生工程机械化施工系统为研究对象，应用随机服务系统理论，研究了系统中铣刨、搅拌、摊铺和压实子系统的运行状态。依据再生工程中铣刨机、搅拌设备、摊铺机和压路机等主要机械的运行规律，分析了各子系统的组成和运行特征，对其运行状态进行定量计算，得到各子系统在稳态时的状态概率表达式，从而推导出子系统中需要服务的运输车数、等待服务的运输车数、运输车辆的等待服务时间等状况指标。最后，基于施工系统的理想工作状态，建立了施工系统初配机群配置方案合理性的数值判断标准。研究表明，各子系统的运行规律和机群合理性判断标准可为建立再生工程机械化施工系统优化配置模型提供理论依据。

Operating law of mechanized construction system in recycling engineering

Taking the mechanized construction system as object, this paper studies the working state of milling, mixing, asphalt paving and rolling sub-system in asphalt concrete pavement recycling engineering using the theory of random service system. According to the operating law of main machinery such as milling machine, mixing equipment, asphalt paver and roller in recycling engineering, this paper analyzes the composition and feature of sub-systems, and calculates their operating states quantitatively, and gets their probability properties expressing equations in stable state. Therefore, the number of vehicles required service and waiting for service, the time waiting for service of vehicles is given. Based on the ideal operating situation of the mechanized construction system, this paper establishes the numerical judge standard about rationality of the construction configuration. The operating law of sub-systems and judge standard of tentative configuration can provide the basis for establishing optimized configuration model in the future.
