  1. The spreading gradation gravelly soil is a kind of clayey coarse - grained soil. it ' s also a soil - rock mixtures. it ' s often divided into fine material and coarse material by the save of 5mm and the granutometric composition affects its project characteristics directly

    寬級配礫質土是一種粘性粗粒土，是天然土石的混合料，它通常以5mm為界被分為粗料和細料兩部分，顆粒組成是決定寬級配礫質工工程特性的主要因素。
  2. The spreading gradation soil analyzed in the article is a cohesive coarse soil. it ' s a kind of crude soil - rook mixtures. it ' s often devided into fine material and coarse material by the save of 5mm and the charge of the two contents affects its project quality directly

    本論文研究的寬級配礫質土指的是黏性粗粒土，是一種天然的土石混合料，其顆粒組成通常以5mm為界分為粗料和細料兩部分，這兩部分組成含量的變化直接影響到它的工程性質。
  3. This article mainly emphasize on the classification of coarse grained soil from the viewpoint of engineering application ( content of coarse grains ), vibrating method is introduced in the shaping. meanwhile, research is made to the water stability and shear strength. through research, following conclusions are obtained : coarse grained gradation is the main factors to determine its shear strength, when the coarse grains content is over 70 % or around, the maximum shear strength appears : the grains itself have a bigger effect on the shear strength

    以往對粗粒土的研究方法多採用擊實法，很少有人研究其抗剪強度特性，本文主要從工程應用的角度（粗粒含量）對粗粒土進行工程分類，成型方法採用振動法，同時對水穩定性、抗剪強度特性進行研究，通過研究得出以下結論：顆粒組成級配特性是決定其抗剪強度的主要因素，當粗粒含量在70左右時，抗剪強度最大；顆粒本身的特性對抗剪強度影響較大，顆粒越堅硬、大小顆粒相差越大、越不均勻、顆粒形狀越呈稜角狀、填築密度越大，抗剪強度就越高；含水量對抗剪強度的影響很小，可以忽略不計。
