无人机摄影测量技术应用于垃圾填埋场形变监测及库容储量分析

快速监测垃圾填埋场固体物质的体积空间变化及准确评估有效库容，可为城市管理者科学决策和合理安排社会资源提供重要依据。无人机摄影测量技术具有机动灵活、数据获取快捷且精度高等优点，在众多领域都有较为广泛的应用。本文以成都市长安垃圾填埋场为例，利用低空无人机摄影测量技术获取填埋库区连续一年的影像数据，并对多期模型数据进行差分处理，分析填埋库区各区域的体积变化量及形变特征；建立库容储量预测模型，研究库容量的变化值与入场物质量的关系，对填埋库区的实际可容纳入场固体物质量进行预测。

Application of UAV photogrammetry technology in deformation monitoring and storage capacity analysis of landfill site

The rapid monitoring of the spatial change of solid material storage in landfill and the accurate evaluation of the effective storage capacity can provide an important basis for city managers to make scientific decisions and rationally arrange social resources. The photogrammetry technology of UAV has the advantages of flexibility, fast data acquisition and high precision, and has been widely applied in many fields. Taking Changan landfill site in Chengdu in Sichuan province as an example, the researchers use the low-altitude UAV photogrammetry technology to obtain the landfill area image data for one year in a row. The volume variation and deformation characteristics of each area in the landfill reservoir area are analyzed based on the model difference. A storage capacity prediction model is established to study the relationship between the variation value of the storage capacity and the mass of the admission objects, and to predict the actual weight of the solid objects that can be admitted into the landfill area.
