Abstract：As an energy base, a farming and animal husbandry production base and a tourist base in northern Shaanxi, China, this region becomes more dynamic in engineering activities. However, only limited studies on the local engineering features in northern Shaanxi were carried out. In order to systematically and comprehensively study the geomorphological and engineering properties of the loess layer in northern Shaanxi, a comprehensive analysis of the loess layer in northern Shaanxi was conducted based on field surveys and related survey data. The analysis results show that the strata in the study area can be divided into Holocene aeolian sand, Upper Pleistocene loess, Middle Pleistocene loess, Neogene and Paleogene rocks. And the northern Shaanxi landscape is divided into loess erosion-tectonic accumulation topography, loess modern structure (deformation) landforms, loess depression landforms, and loess erosion landforms. Engineering properties (including collapsibility, permeability, mechanical properties etc.) of loess mass from north to south in northern Shaanxi are quite different due to different depositional ages and occurrence environment. The research of landform and engineering characteristics in this paper not only has a close relationship with engineering geology, hydrology geology and environmental geology, but also has important guiding significance in the construction of ecology, economy, and national defense in the loess area of northern Shaanxi Province.
