In order to elaborate the app licability of osl to loess, especially single aliquot regenerative protocol ( sar ), involving stimulation of the same disc with an infra - red laser diode followed by blue leds to polymineralic fine - grains of loess, such explanations as light bleaching, preheat, anomalous fading, prior - ir exposure were investigated in this paper. for drawing adequate coarse grains from loess, quartz and feldspars, as well as loess, were etched by hydrofluoric acid and fluorosilicic acid. the sequence of ages of holocene loess in weihe rivier basin has been established by single - aliquot ( sar ) and multiple - aliquot using fine - grains and sar using coarse - grains

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。
