在地球各大陆上工程地质条件水平和垂直上的变化反映出它们的区域性,它受控于该地区的热量、湿度及其比率。这就是在类似地质结构的地区中,不同的纬度和海拔高度形成了不同的工程地质条件的原因。引入工程地质区这个概念的目的在于说明工程地质条件的区域性。工程地质区一词的意义是指一个大的工程地质地区或省,在其中主要由水的形态决定的岩土状态是均一的并从工程地质观点来看具有区域稳定性。已经确定了以下工程地质区类型:永久性的多年冻土区域、多年冻土和融化沉积共存区域,以及融化和不冻岩石区域,它们再细分为亚区。工程地质条件区域性概念要考虑的主要问题有:分区原则、工程地质区域的类型和种类、地球各大陆上工程地质区域的空间分布规律性、“理想”大陆上的分布模型。
The horizontal and vertical changes in engineering geology on all continents reflect their regionality, which is governed by the heat, humidity and their ratios in the area. This is why, in similar geological formations, different geological conditions have been formed at different latitudes and altitudes. The purpose of introducing the concept of engineering geological area is to illustrate the regional nature of engineering geological conditions. The meaning of the term engineering geology refers to a large area of engineering geology or geology in which the geotechnical conditions, which are predominately determined by the morphology of the water, are uniform and have regional stability from an engineering geological point of view. The following types of engineering geological areas have been identified: permanent permafrost areas, permafrost and thawing deposits coexisting areas, and melting and non-freezing rock areas, which are subdivided into subregions. The main issues to be considered in the regional concept of engineering geological conditions are: zoning principle, types and types of engineering geological areas, spatial distribution regularity of engineering geological areas on all continents, and “ideal” distribution model on the mainland.
