摘要
以北京六环以内的核心城区为例,在系统分析研究区地质条件的基础上,综合考虑敏感因素对地下空间开发地质适宜性的影响,从而构建地下空间适宜性评价指标体系,并利用层次分析法确定评价指标权重,最后采用模糊数学综合评判法对研究区地下空间开发适宜性进行了评价。结果表明:研究区地下空间开发适宜性以适宜性好和较好为主,占比60.11%,地质环境条件较好,总体比较适宜地下空间开发,活动断裂、水源地分布和古河道分布3个敏感因素是制约研究区地下空间开发的主要地质因素。
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.
