Suitability Evaluation of Subsurface Space Development and Utilization in Langfang North Three Counties, Hebei Province
This article is on the basis of the analysis of geological environmental factors such as topography, engineering geology, hydrogeology, and geological environmental issues in the Langfang north three counties, Hebei Province. According to the study of the interaction between geological environment elements and subsurface space development, a geological environment suitability evaluation index system for different depths of subsurface space development has been established. This article evaluates the suitability of the development and utilization of the shallow (0 ~ −18m), medium(−22 ~ −50 m) and deep (Below 70 m) subsurface space at different depths in this area according to the four levels of unsuitable, less appropriate, more appropriate and appropriate by the analytic hierarchy process. The results show that more than 70% of shallow and deep layers the study area is suitable or more suitable for the development and utilization of subsurface space. Among them, the suitable area for shallow subsurface space development accounts for 31.23%, the more suitable area accounts for 53.63%, the less suitable area accounts for 12.27%, and the unsuitable area accounts for 2.87%; The middle suitable area accounts for 7.45%, the more suitable area accounts for 46.61%, and the less suitable area accounts for 34.48%; The proportion of unsuitable areas is 11.95%; The deep suitable area accounts for 30.81%, the more suitable area accounts for 43.86%, and the less suitable area accounts for 22.72%; The proportion of unsuitable areas is 2.62%. The evaluation results can provide geoscientific basis for the planning of subsurface space development and utilization in the study area.
