摘要
矿山生态修复项目中工程量复核是工程质量的全方位保障,也是项目竣工验收的基础和前提。针对矿山生态修复项目工程量特点和复核工作需求,以边坡喷播面积、台阶土石方挖填方量和平场覆土量等3项复核指标为研究对象进行工程量复核工作研究。本项目以无人机航测点云数据为研究基础,利用点云数据优势,结合矿山生态修复项目地形及工程特点,采用经验贝叶斯克里金法和优化的分区域三角网模型建立了完善的复核模型。通过与散点法和DSM法进行数据精度对比分析,得出本研究方法精度高且能够满足快速精确的复核工作需求,具有良好的应用推广价值。
The engineering quantity review in the mine ecological restoration project is the all-round guarantee of engineering quality,and also the basis and premise of project completion acceptance.According to the engineering quantity characteristics and review work requirements of the mine ecological restoration project,the engineering quantity review work is studied with three review indexes as the research object,such as the spraying area of slope,the excavation and filling amount of earth and stone on the stairs and the amount of soil cover in flat field.This project takes the UAV aerial point cloud data as the research basis,takes advantage of the point cloud data,combines with the topography and engineering characteristics of the mine ecological restoration project,and uses the empirical Bayesian Kriging method and the optimized sub-regional triangulation model to establish a perfect review model.Through the comparative analysis of the data accuracy with the scatter method and the DSM method,it is concluded that the research method has high accuracy and can meet the requirements of fast and accurate review work,which has good application and promotion value.
