工程项目流水施工是一种常用和有效的施工组织方式,一般分为有节奏流水施工和无节奏流水施工。在概括总结两种流水施工特点的基础上,重点阐述无节奏流水施工进度计划横道图各相邻施工过程流水步距的理论计算,特别是在其网络计算时需要处理的特殊问题。最后通过实证研究,得出结论:凡是流水步距不等的流水施工,必须将流水步距以虚拟工作的形式引入网络计算的逻辑关系。
Construction project flow construction is a common and effective way of construction and organization, are generally divided into rhythmic flow construction and unmanaged flow construction. On the basis of summarizing the characteristics of the two kinds of water flowing construction, this paper mainly elaborates the theoretical calculation of the water flowing step distance of the adjacent construction process in the rhythm flow construction schedule roadmap, especially the special problems that need to be dealt with in the network calculation. At last, through empirical research, we conclude that for all the water flowing construction with different water flow steps, the water flow step must be introduced into the logical relationship of network calculation in the form of virtual work.
