    Geological environment suitability assessment of underground space development in Nanchang City

    • 摘要: 地下空间资源是未来城市发展的重要空间资源,也是可持续发展战略中不可缺少的部分。为了支撑南昌市地下空间的科学开发,基于地质调查成果,从地形地貌、工程地质条件、水文地质条件、活动断裂与地震效应、环境地质问题5个方面对南昌市地质环境影响因素进行识别,构建地下空间开发地质适宜性评价指标体系,采用层次分析法和灰色关联分析法建立数学模型,对不同深度地下空间的地质适宜性进行了评价。评价结果显示,研究区中层地下空间地质条件复杂,浅层和深层地下空间更适宜开发。该结果为南昌市地下空间专项规划的编制提供了技术支撑。

       

      Abstract: Urban underground space is an important spatial resource for future cities and an indispensable part of sustainable development strategy.In order to support the scientific development of underground space in Nanchang, the geological environment influencing factors were identified from five aspects, including topography and geomophology, engineering geological conditions, hydrogeological conditions, active faults and seismic effects, and environmental geological issues.Based on the construction of an evaluation index system for the geological suitability of underground space development, the geological suitability of underground spaces at different depths was evaluated through analytic hierarchy process and grey relational analysis.The results show that the geological conditions of the middle underground space in the study area are complex, and the shallow and deep layers are more suitable for development.This result provides technical support for the preparation of the special plan for underground space in Nanchang.
