不同泥岩比例下粗粒土的颗粒破碎

Coarse-grain soil particle breakage under different mudstone ratio

通过对混合土料进行大型三轴不固结不排水(UU)压缩试验,研究了不同泥岩比例对试料颗粒破碎率的影响,结果表明随着泥岩比例的增加,土体的颗粒破碎率呈现降低的趋势。

Through carrying out consolidated untrained triaxial compression test（ UU）of concrete mixture,the thesis studies the impact of differ-ent mudstone ratio upon particle breakage ratio. Results show that：the coarse-grain soil particle breakage ratio will reduce with the mudstone ratio increasing.
