对延安新区重塑Q3黄土进行了控制不同含水率、不同干密度的直剪试验，研究了含水率、干密度对黄土抗剪强度的影响，试验结果表明：黄土的强度主要受含水率的影响；随着干密度的增大，黄土粘聚力呈指数增长，内摩擦角增大，抗剪强度总体增大；随着竖向荷载的增加，黄土的抗剪强度得到提高。

The Yan’ an New District remolded Q3 loess direct shear tests were carried out by control the different moisture content and different dry density. The influence about the moisture content and the dry weight density on the loess shearing strength was studied. The results as fol-lows, the strength of loess is mainly affected by the moisture content. As the dry density increases, cohesion of loess increases exponentially, the angle of internal friction increases, the shear strength increases entirely. As the vertical loads increases, the shear strength of loess increases.
