Aiming at the construction scenario of mutual interference of two linear active railway projects,the spatial expression of double lines in construction sections is reconstructed based on the linear planning method,and a time-construction section model is established.Considering constraints such as time,space,and construction resources,internal constraints of each line are constructed as the basis to estab-lish inter-line constraints.A railway construction schedule optimization algorithm for two mutual interfering lines was constructed using the standard genetic algorithm with the allocation of construction resources within each line and section as the independent variable.The algorithm can automatically output the resource allocation under the optimal construction period conditions,and create a corresponding linear plan chart based on the optimal duration and resource allocation.The final simulation results show that the duration optimization model and the algorithm can efficiently obtain the construction schedule of railway projects with double lines interfering with each other under the shortest construction period,which verifies the rationality of the model and the effectiveness of the algorithm in this study.
