The geological environment suitability assessment of Guangzhou underground space resources

摘要

Based on a large collection and analysis of the engineering geological data of Guangzhou, using the analytic hierarchy process, fuzzy comprehensive evaluation method and the spatial analysis technology in GIS, according to the shallow (0 ～15m), medium (15 ～30m) and deep (30 ～50m), we evaluate and analyze the urban underground space in Guangzhou respectively. The index system for the evaluation of urban underground space resource with three themes (include the subject level of engineering geological condition, hydrogeology condition and rock -soil mass condition), 13 items (include the topography and geomorphology condition, the regional geological background, etc.) and the fuzzy comprehensive evaluation model are established.
