通过对工程勘察资料分析，就三门峡地区自重湿陷性黄土的工程特性，从物理性质和化学性质方面进行了研究并从各个方面与兰州黄土进行了对比，认为三门峡黄土虽然与兰州黄土湿陷性质相同，但反映到工程上，优于兰州黄土。 Through the analysis of engineering survey data, the engineering characteristics of self-weight collapsible loess in Sanmenxia area are studied in terms of physical and chemical properties and compared with the loess in Lanzhou from all aspects. Although the loess in Sanmenxia has the same characteristics as loess in Lanzhou The same, but reflected in the project, better than Lanzhou loess.
