《湿陷性黄土地区建筑规范》提供了湿陷性黄土工程地质分区略图,它使人们对全国范围内的湿陷性黄土性质和分布有一个概括的认识和了解。但对具体工程,黄土湿陷性因所处环境和典型地貌特征的差别,表现出独特的亚区特征。河南巩义黄河高阶地黄土便是其中一例,其湿陷性特征显著区别于地质分区(V区)的一般规律。通过十余年来在这一地区多个大型工程实践,对本区黄土湿陷特征的认识从最初的怀疑、争论,到最终澄清了争论与误解,经历了一个漫长的时期,确定了其典型的亚区特征。
The Code for Construction of Collapsible Loess Regions provides a schematic view of collapsible loess engineering geological zoning that gives a general understanding and understanding of the nature and distribution of collapsible loess nationwide. However, for a specific project, loess collapsibility shows unique sub-regional characteristics due to the difference between the environment and the typical topography. An example is the high-grade loess of the Yellow River in Gongyi City, Henan Province. Its collapsible characteristics are significantly different from the general laws of the geological division (V-zone). Through more than ten years of large-scale engineering practice in this area, the understanding of the characteristics of loess collapsing in this area from initial suspicion and controversy to the final clarification of controversy and misunderstanding has come a long period of time and its typical Asian characteristics.
