| Geological Safety and Risk Analysis of Yinchuan Urban Underground Space Development |
| The use of urban underground space is affected and restricted by the geological environment. Evaluation of the safety of the geological environment is the foremost issue for the development of underground space. We conducted a geological resource investigation and regionalization of the Yinchuan urban area, and selected the evaluating factors namely, earthquakes (including active faults and site seismic effect), sand liquefaction, rich water sandy aquifer, soil-bearing capacity and surface building load. The geological risk of each factor was analyzed. Subsequently, a comprehensive evaluation of the factors of geological safety and risk in underground space development was conducted using the analytic hierarchy process and a more flexible multiplication scale method. The results showed that in the Yinchuan urban area, the main controlling factors are earthquake and sand liquefaction for the underground space development. The high-, moderate-, and low-risk areas comprised 4.10%, 19.69%, and 41.07% of the urban area. The very low-risk area comprised approximately 35.13% of the urban area. This study provides an important geological reference for underground space development and construction in the Yinchuan urban area. |
