如何通过试验研究，进一步认识粗粒土的工程性质，更好地服务于土木工程建设是本文研究的重点。 - Coarse grained soil is composed of sand and gravel , stone residual , blasted stones etc . , which has a characters of less cohesive force among grains and strong ability of water penetration . it is a kind of soil of loose grain structure with better utilization properties in the engineering
粗粒土是指砂砾石、砂卵石、石渣、爆破开采的石料等粗颗粒土石混合料，具有粗颗粒间粘结力小、透水性强的性质，是一种松散的颗粒状结构，具有良好的工程使用性能。 - 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。 - Then , using the large - scale coarse grained soil test system , the relative density and direct shear characteristics of sand - gravel mixtures in different size distribution were tested . and the soc affecting mechanism derived from non - uniform granular material was discussed . the phenomenon can be observed that , along with the increase of non - uniform degree , the accumulate structure will become more complex , and the sliding resistance among sands will grow accordingly
在此基础上，利用大型粗颗粒实验系统，测定不同非均匀系数沙石材料的相对密度和直剪特性，探讨了颗粒非均匀程度对自组织临界性影响的具体物理力学机制：随着非均匀度的增大，散粒堆积体的颗粒结构空间分布堆积方式的多样性增大，颗粒滑动的摩擦耗能增加。
