Abstract：Research purposes: In order to reduce the construction period delay caused by rework of technical interface process in railway project schedule management, a buffer management method of key technical interface process considering different overlapping relationships is proposed. Research conclusions:(1) Based on the concept of technical interface exchange and PDCA cycle theory, a full life cycle model of railway engineering technical interface exchange is built. Through analyzing the interface information exchange process under different overlapping relationships, it is found that information transmission is the fundamental reason for affecting the construction period. (2) The DSM matrix is used to quantify the rework risk and probability caused by technical interface information interaction, determine the rework time and resource tightness, and take Bayu Tunnel of Lhasa-Linzhi Railway and Bayu Yarlung Zangbo River Third Line Bridge as examples to calculate the buffer size and duration of technical interface. (3) The results show that the buffer of construction period is 18.56 days, and the total construction period is 112.63 days. Compared with the method that does not consider the different overlapping relationships of interfaces, the total interface duration is reduced by 5.23%, that is, this method can effectively shorten the duration and promote the on-time completion rate of the project. (4) This method can provide a reference for the optimization and control of the progress of railway engineering technical interface.
