作者多年来在黄土地区进行了考察和勘探并采集了各类黄土样品，在室内外进行了黄土的物理力学性质的试验研究，取得了大量的关于黄土特性的资料．根据这些研究结果，探讨了黄土的物理力学指标与黄土易损性的关系及其区域分布规律，从而研究它与黄土地区的地质灾害和震害的关系． Over the years, the author has conducted exploration and exploration in the loess area and collected various types of loess samples. The physical and mechanical properties of loess have been experimentally studied indoors and outdoors, and a great deal of information has been obtained on the loess properties. Based on these results, the relationship between loess physical and mechanical properties and loess fragility and its regional distribution are discussed, and the relationship between it and geological disasters and earthquake damage in the loess area is studied.
