| 摘 要： | 传统颗粒分析因难于对巨粒组进行筛分测试,而忽略了其对岩土物理参数的影响。该研究应用数字化三维激光扫描技术,增加巨粒组的颗粒分析。通过数据采集、点云数据配准、噪音点去除和颗粒轮廓提取获得某堆积物地表数据。并结合室内颗粒分析结果绘制全颗粒累计曲线。与传统累计曲线比较,该曲线不均匀系数变大,级配变好,孔隙度和渗透性发生变化。

| Abstract: | The numeral 3D laser scanning technology was used here to add giant particle analysis which was absent in the traditional granularity analysis.Data of a debris surface were acquired by collecting,registrating point-cloud data,removing noise point and drawing particle contour.A complete cumulative curve was drawn on these data and an indoor analysis.Compared with the traditional cumulative curve,this one shows a less uniformity,a better graduation,a different overall porosity and permeability. |
