摘　　要：装配式混凝土建筑在我国受到大力推广,与传统现浇建筑相比,装配式建筑的施工过程将传统的现场湿作业改为吊装和湿作业结合。因此,施工现场的要素不仅仅有原来湿作业的钢筋、砂、石、水泥等材料,还增加了各种类型的预制构件,这对施工现场规划方案产生了一定影响。基于离散事件模拟技术建立能够对装配式混凝土建筑施工现场规划方案进行评价和决策的方法。离散事件模拟用于将施工现场的各功能区域参数化并模拟不同施工现场规划方案下各功能区域的形状、位置和大小对施工过程的影响。并将该方法应用于某装配式混凝土建筑进行实例分析,应用结果说明,建立的方法能够有效地选择出具有优良施工表现的装配式混凝土建筑施工现场规划方案,也为以后的相关研究提供了参考。Precast concrete(PC)buildings have been widely promoted in China.Compared to traditional cast-in-situ concretebuildings,construction of PC buildings includes not only concrete casting but also PC component hoisting.Therefore,not only theconcrete casting materials such as rebar,sand,stone and cement,but also the PC components can be seen at construction sites of PCbuildings,which affects the construction site-layout.To address this issues,this research builds a Discrete Event Simulation(DES)-basedmethod to compare and optimize the construction site-layout of PC buildings.The DES is used to parameterize the functional area atconstruction site and simulate the impact of the shape,location,and size of the functional area in construction process.The proposedmethod is applied to a case building to verify its effectiveness.The results show that the proposed method can effectively improve theconstruction performance of the construction site-layout schemes of PC buildings.This research provides reference for the future study.
