在我国广大的华北、西北地区,分布有厚度不同的黄土,由于自然地理条件,塑造成独特的地貌和地质作用形成的各种地理地质现象,改变了原有的地表形态。将完整的地表,切割破碎不堪,形成复杂的沟谷,深堑峁、塬的地形。黄土的工程性质,同样的具有特殊的性能,它与一般土壤有所不同。就道路工程要求,可分为松散结构黄土和密实结构黄土两类。松散桔构黄土为近代的各种成因的黄土堆积物,由于成因复杂地貌条件不同,具有不同的稳定性,但共同的性质是:结构疏
In the vast northwestern and northwestern regions of China, loess with different thicknesses is distributed. Due to the natural and geographical conditions, various geo-geological phenomena formed by unique landforms and geological features have changed the original surface morphology. The complete surface, cutting fragmented, the formation of complex valleys, graves, highland terrain. Loess engineering properties, the same with special properties, it is different from the general soil. On the road project requirements, can be divided into two types of loose structure of loess and dense structure of loess. Loose orange loess is a kind of loess sediment with various causes in modern times. Due to complex geological conditions, it has different stability, but the common properties are: structural sparse
