堆石坝试坑三维点云优化重构与体积快速计算方法及应用
Optimized reconstruction of 3-D point clouds of rockfill dam test pits with fast volume calculation method and its application
摘要
Abstract
Trial pit test is a standard method for evaluating rockfill compaction in dam construction.The advent of 3D laser scanning technology offers a rapid,accurate alternative to the traditional water filling method for measuring the pit's volume.This study develops a new method that integrates data acquisition,registration,and fast volume calculation using 3D laser scanning.Tested against the standard model and a laboratory experiment,the method captures the irregular distribution of rockfill particles effectively;Optimizations in large-scale in-situ tests have achieved volume measurement errors roughly within 5%.Field applications in dam projects further validate the method's efficiency,significantly reducing inspection time and having the potential to replace traditional methods.关键词
