黄土地区公路边坡土壤质地分析对于设计和维护边坡稳定性进而确保公路交通安全具有重要意义。本研究选取黄土地区代表性路段,对不同区域、不同年限、不同形式和不同位置的边坡土壤质地进行了系统的分析和比较。实验结果表明,不同黄土地区边坡土壤粒度存在差异;相比于填方路段,挖方路段的表层土壤质地更为接近原状土壤。本研究结果对于设计和维护黄土地区公路边坡稳定性具有重要参考意义。 Analysis of soil texture of highway slope in loess area is of great importance for the design and maintenance of slope stability and thus ensuring highway traffic safety. In this study, representative sections of loess area were selected to systematically analyze and compare the slope soil texture in different regions, different years, forms and locations. The experimental results show that there are differences in the soil particle size of slopes in different loess areas. The surface soil texture of excavation section is closer to that of undisturbed soil. The results of this study are of important reference for the design and maintenance of highway slope stability in loess area.
