| Geological Suitability Evaluation of Underground Space in Beijing Urban Area Based on Fuzzy Mathematics |
| Taking the core urban area within the sixth ring road of Beijing as the study area, this study examined the influence of sensitive factors on the development of underground space, based on a system analysis of regional geological conditions. An appropriate suitability assessment index system for the exploitation and use of the underground space was established. The weights of indexes were determined using the analytic hierarchy process, and a fuzzy mathematics comprehensive evaluation method was used to evaluate the suitability of underground space as a resource in this region. The results show that 60.11% of the underground space in the study area is suitable for development; therefore, the geological conditions are relatively favorable for underground space development. Three sensitive factors–active fault, distribution of water source and distribution of palaeochannel–were found to be the main geological factors restricting the development of underground space in the study area. |
