| description | The invention provides a rock mass deformation amount and deformation trend description method based on three-dimensional laser scanning point cloud data, and the method specifically comprises the steps: carrying out the three-dimensional laser scanning test of a rock mass, and obtaining the to-be-evaluated rock mass point cloud data with high precision; calculating the distance between each point of the point cloud, limiting the range of a fitting plane, and calculating the positive and negative distances between each point and the optimal fitting plane; and drawing a relative deformation scatter diagram of each point. According to the rock mass deformation and trend description method, the rock mass surface information is directly processed through three-dimensional laser scanning, the danger area in single-period point cloud data can be visually reflected, two-period relative deformation data of the danger area can be compared to determine expansion of the deformation development stage and the deformation |
