基于三维模型的边坡土方计算分析
Calculation and Analysis of Slope Earthwork Based on 3D Model
摘要
Abstract
The traditional GPS-RTK method has some limitations in earthwork calculation,and there are differences in the results calculated by different methods.Taking a high and steep slope in a mine site as the research object,we used the DTM method,grid method and section method to calculate the earthwork based on the real scene 3D model,and compared and analyzed the results.The results show that both DTM method and grid method are accurate and reliable under the case of large extraction density of elevation points.However,as the extraction density of ele-vation points decreases,the accuracy of grid method decreases rapidly and the accuracy of DTM method decreases slowly.In contrast,the section method is less affected by the change of section spacing,and the calculation results are relatively stable.关键词
