针对线状活动铁路工程施工场景，在双线相互干涉条件下，基于线性计划方法，对双线的空间表达以施工区段为单位进行重构，建立时间-施工区段模型，考虑时间、空间、施工资源等约束，构建线路内部约束条件，再以线路内部约束为基础，建立线路间约束条件。结合标准遗传算法，以各条线路各区段内施工资源配置情况为自变量，构建双线相互干涉条件下铁路工程施工进度计划工期优化算法，能够在算法中自动输出最优工期条件下的资源配置情况，根据算法输出的最优工期和资源配置情况制作对应的线性计划图。算例仿真结果表明，工期优化模型和算法能够高效获得最短工期下双线相互干涉的铁路项目施工进度计划，验证了本文模型的合理性和算法的有效性。

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 establish 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.
