摘要： 基于异节拍流水施工可以按照不窝工有间歇(即分别流水)或不间歇有窝工的形式组织，研究了异节拍流水 施工中流水节拍产生两种流水工期差异的条件，及差异值与流水节拍值的关系。结果表明:流水工期差异为当m 个施工段需要n道工序进行流水施工时，任意连续的3个流水节拍值中，若位于中间的流水节拍值为最小值，不窝 工有间歇的流水工期(T)与不间歇有窝工的流水工期(T')的关系是T＞T'，并且其工期差值与3个连续流水节拍中 的最小值和另一侧的流水节拍最大值的差值有关，是m-1的倍数;否则，T=T'。

Abstract: On the basis of different flow construction and according to the form of non-idleness and interval or non-interval and idleness，different flow construction results are researched and the difference in two flow duration and the relationship between D-value and flow duration are also studied. The results show that the difference in flow duration is that when m construction sections and n work procedures are put into flow construction，there is takt time among any three continuous flows， and the middle takt time is the minimum. The relationship between flow duration ( T) of the non-idleness and interval and the flow duration ( T') of the non-interval and idleness is that T ＞ T'，and the D-value of them is related to the D-value between minimum of the three continuous flow takt time and the maximum from another side，which is the multiple of m-1， otherwise，T = T'.

Key words: flowduration, idleness, interval, flowconstruction, D-valueofconstructionperiod
