Method for generating blindage range above tunnel

The invention discloses a method for generating a blindage range above a tunnel, and relates to the field of constructional engineering. The method comprises the following steps: establishing a tunnel model of a tunnel based on three-dimensional data of the tunnel; obtaining an oblique photography model of a blindage above the tunnel; based on the footage length of the tunnel, a target point is determined in the tunnel model, and the safety coefficient of the target point is smaller than a preset safety coefficient; projecting the target point to an oblique photography model to generate a first projection point; and generating a blindage range above the target point in the tunnel model by taking the first projection point as a circle center and combining a preset radius. By implementing the technical scheme provided by the invention, the precision and efficiency of obtaining the ground surface range above the tunnel can be improved. 一种用于生成隧道上方掩体范围的方法，涉及建筑工程领域领域。在该方法中，包括：基于隧道的三维数据，建立隧道的隧道模型；获取隧道上方掩体的倾斜摄影模型；基于隧
