摘要
以我国西部某高拱坝边坡开挖面为例,利用三维激光扫描技术快速、全面地获取开挖面点云数据信息,制定合理的数据采集流程,对所采集的开挖面空间数据信息进行处理并建立数据库。在施工现场直接利用点云数据对边坡开挖质量进行实时评价,实现了高拱坝边坡开挖质量快速评价的目标,对加快施工进度和保障施工质量具有重要的工程意义。
Taking a high arch dam slope excavation surface in western China for an example, 3D laser scanning technology is used to obtain the cloud data of excavation face point fast and comprehensively and develop reasonable data collection process. Spatial data information of excavation face is processed and built a database. Technical staff can directly utilize the point cloud data to accomplish the real-time evaluation of slope excavation quality at the construction site so as to achieve the rapid evaluation goal of high arch dam slope excavation. It has important project significance for speeding up construction progress and ensuring construction quality.
