【摘要】 城市地下空间开发利用地质环境适宜性评价涉及多方面的复杂不确定因素。以江苏宜兴为例,将影响城市地下空间开发利用的因素划分为区域稳定性、地形地貌、水文地质条件、不良土体、地质灾害等,运用层次分析法确定各指标的权重,将各个指标数值化,结合灰色关联度分析法,根据灰色数学理论计算出评价母序列与各评价序列之间的关联度,最终确定研究区地下空间开发利用地质环境适宜性等级。结果表明,宜兴约有55%面积的地下空间具备良好的开发前景,约40%面积的地下空间开发前景一般,仅有5%面积的地下空间开发利用适宜性差。研究成果可为宜兴市地下空间开发的规划、设计、施工等提供参考。更多还原

【Abstract】 The evaluation of the suitability of geological environment for the development and utilization of urban underground space involves complex and multi-faceted uncertainty factors. Taking Yixing City of Jiangsu Province as an example,the factors affecting the development and utilization of urban underground space are divided into regional stability,topography,hydrogeological conditions,undesirable soil,geological disasters,etc. The weight of each indicator is determined by hierarchical analysis,and the numericalization of each indicator is combined with the gray correlation analysis method to calculate the correlation between the evaluation master sequence and the other evaluation sequences,in order to determine the suitability level of geological environment for the development and utilization of underground space of the study area. The results show that about 55% of the underground space in Yixing has good development prospects,about 40% has ordinary prospects,and only 5% has poor prospects. The research results can provide reference for the planning,design and construction of underground space development in Yixing City.更多还原
