    Abstract: 在篩分析時,當顆粒尺寸大於篩網孔徑時會被停留在該號篩網上;而顆粒較小則會通過。依序在每一篩網上重複進行上述的篩選邏輯。這與碎形理論中,量測碎形維度(D)的方格覆蓋法之以大小不等方格尺寸之網格(Mesh)分別覆蓋到同一組顆粒群體上,再分別計算每一種尺寸方格之顆粒總覆蓋格之道理極為相似。本文仿照碎形理論之方格覆蓋法分析邏輯,針對卵礫石篩分析資料,以雙對數型態重新表現粒徑分布曲線特性,以求得大小組成顆粒之碎形維度D,借碎形維度D值可用以反映顆粒間填充之程度。
    In fractal theory, the box-counting method uses the grids in various sizes to cover the fractal object and obtains the box dimension. This sequential counting concept is analogous to the sieve analysis test using stacked sieves. This study applies the box-count method to describe the particle size distribution of gravel. The particle-size distribution curve obtained from a sieve analysis is re-arranged in a double-logarithmic plot, according to a fractal model, to obtain its fractal dimension of the particle collection.
