The invention discloses a coevolution-based railway three-dimensional linear intelligent design method, which comprises the following steps of: firstly, establishing two three-dimensional linear design objective functions, and according to the line grade of a railway, the constraint conditions of a plane and a longitudinal section and the unit price cost, solving the number and parameters of plane intersection points and the number and parameters of longitudinal section grade change points of the three-dimensional line shape based on the ArcGIS platform at the same time through a coevolution difference algorithm, and achieving intelligent design of the railway three-dimensional line shape. The three-dimensional line shape using the intelligent design method can comprehensively consider engineering cost and operation cost, can well avoid obstacles and adapt to terrains, and provides early-stage design reference for engineering designers. 本发明公开了一种基于协同进化的铁路三维线形智能设计方法，首先建立两个三维线形设计目标函数，依据铁路的线路等级、平面和纵断面的约束条件、单价费用，采
