摘　　要：地下空间开发具有不可逆性,不合理的开发将对宝贵的地下资源造成巨大浪费。为提高地下空间资源的合理开发与有序利用,有必要对地下空间开发利用适宜性进行前期评价。以地下空间多资源协同开发利用与地质环境问题互馈响应为立足点,提出了一种基于“地质资源”、“地质结构”、“地质问题”的评价模型——地质资源评价和地下空间开发难度评价,并采用层次分析法、模糊综合评判法、限制性要素扣除法等数学方法进行分层综合评价,最终建立了一套适合于山前冲积平原型城市地下空间资源开发利用的地质适宜性评价模型。评价结果显示,研究区浅层地下空间因已有构筑物的影响,适宜性较差,而中深层地下空间更适宜开发。该结果可为研究区地下空间开发规划和建设提供科学依据和有效指引,从而加强城市地下空间开发利用规划的合理性、科学性。The development of underground space is irreversible,and the unreasonable development will cause a huge waste of valuable underground resources.In order to improve the rational development and orderly utilization of underground space resources,it is necessary to make a preliminary evaluation of the suitability of underground space development and utilization.Based on the cooperative development and utilization of multi-resources in underground space and the reciprocal feed-back response of geological environment problems,an evaluation model based on"geological resources","geological structure"and"geological problems"was proposed,that is,geological resources evaluation and difficulty evaluation of underground space development.Finally,a set of geological suitability evaluation model suitable for the development and utilization of underground space resources in piedmont alluvial plain city was established by using mathematical methods such as analytic hierarchy process,fuzzy comprehensive evaluation method and deduction method of restricted factors.The evaluation results show that the shallow underground space in the study area is not suitable for development due to the influence of existing buildings,while the middle-deep underground space is more suitable for development.The results can provide scientific basis and effective guidance for the development planning and construction of underground space in the study area,thus reflecting the rationality and scientificity of urban underground space development and utilization planning.
