| 摘 要： | 黄土作为一种特殊性岩土,具有特殊的工程地质性质。在黄土地区的公路建设中,过去人们常常对黄土重视程度不足,未对黄土地基进行处理,加之排水设施不完善,造成了工程建成后病害不断。黄土在宁夏回族自治区广泛分布,随着高速公路向宁南山区的延伸,高速公路也逐渐进入宁夏回族自治区的黄土地区,对该地区黄土的工程性质进行深入分析很有必要。

| Abstract: | The loess occurs as a special kind of earth on a wide range of scales in Ningxia,China. However,little was known before about the importance of the loess in the construction of highways in the loess areas. The present paper deals with physical and chemical properties,especially the self-collapsibility of the loess along the HeichengHaiyuan Expressway in Ningxia on the basis of relevant engineering experimental data. The results of research may improve our knowledge of engineering geology of the loess and will assist in the construction of highways in the loess area. |
