为了得到击实黄土的抗剪特性,以不同粘土含量(10%,20%,25%和30%)的四个黄土土样为试验样本,分别进行了颗粒分析试验、标准击实试验、直剪试验,试验表明:粘粒含量影响黄土的击实效果,直剪试验表明粘粒含量改变了黄土的受剪特性但对黄土的内聚力和内摩擦角的影响较小。
為瞭得到擊實黃土的抗剪特性,以不同粘土含量(10%,20%,25%和30%)的四箇黃土土樣為試驗樣本,分彆進行瞭顆粒分析試驗、標準擊實試驗、直剪試驗,試驗錶明:粘粒含量影響黃土的擊實效果,直剪試驗錶明粘粒含量改變瞭黃土的受剪特性但對黃土的內聚力和內摩抆角的影響較小。

In order to evaluate the mechanical characteristics of loess,the following laboratory tests were conducted on four loesses having differ-ent clay contents(10% ,20% ,25% ,and 30% ),the soil index test,the compaction test,the direct shear test. Test results show that clay con-tent influences the effect of compacted,the direct shear tests show that clay content influences the shear characteristics of loess,but has little effect on the cohesion and internal friction angle of loess.
