摘要
水库库容复核是水库管理中的重要内容。针对常规库容复核方法耗时耗力、安全性不高的问题,该文采用机载LiDAR+无人船+RTK实测的多源数据融合方法,创新性地引入实测数据验证和补充其他数据源,并构建库区BIM模型,进行库容复核,以宜兴市油车水库为例,实现批量库容复核计算。经验证,发现机载LiDAR点云成果可靠性较高,可以提升山区库容复核的效率和安全性;实测数据对水陆交界处的补充,可以有效提升库容复核的准确度。
Reservoir capacity review is an important part of reservoir management.In view of the problems that the conventional storage capacity review method is time-consuming,labor-intensive,and low safety,this paper adopts a multi-source data fusion method of airborne LiDAR+unmanned surface vessels(USVs)+RTK field measurement,innovatively introduces measured data to verify and supplement other data sources,and constructs the reservoir area BIM model to carry out storage capacity review.Taking Youche Reservoir in Yixing City as a case study,the reservoir capacity was recalculated.Validation revealed that the airborne LiDAR point cloud data demonstrated high reliability,significantly enhancing both the efficiency and safety of capacity verification in mountainous reservoir areas.Furthermore,the supplementary field measurements effectively captured the land-water interface,leading to a substantial improvement in the accuracy of the capacity verification results.
