| 8. | 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 以往对粗粒土的研究方法多采用击实法,很少有人研究其抗剪强度特性,本文主要从工程应用的角度(粗粒含量)对粗粒土进行工程分类,成型方法采用振动法,同时对水稳定性、抗剪强度特性进行研究,通过研究得出以下结论:颗粒组成级配特性是决定其抗剪强度的主要因素,当粗粒含量在70左右时,抗剪强度最大;颗粒本身的特性对抗剪强度影响较大,颗粒越坚硬、大小颗粒相差越大、越不均匀、颗粒形状越呈棱角状、填筑密度越大,抗剪强度就越高;含水量对抗剪强度的影响很小,可以忽略不计。 |
