根据南宁市区域地质、岩土性状、地质灾害等研究成果并结合南宁市地下空间开发利用现状,分析了城市地下空间开发地质环境适宜性评价的影响因素,运用层次分析法从地质结构、地形地貌、岩土体特征、水文地质条件、地质灾害与环境地质问题等5方面为准则层建立分析模型;在确定各指标因素权重的基础之上,运用模糊综合评判法,评价地下开发拟建区的地质环境适宜程度.南宁市地下空间开发的地质适宜性可划分为4个等级:最适宜、适宜、次适宜及不适宜,分别占研究区域面积的20%、30%、40%和10%.

The factors which influence the geological environment suitability assessment of underground are analyzed.In the research of geological rock and soil property,geological disasters,and the current utilizing situation of underground,AHP method is adopted to set up the analysis model based on the geologic structure,topography,rock and soil characters,hydro geologic conditions and geological disasters.The theory of Fuzzy comprehensive evaluation is used to evaluate the suitable intensity of underground geological environment.Studies show that the application results are in consistent with the objective reality,and give a reference to the geological environment suitability assessment in underground development.The geological suitability of underground space development in Nanning can be divided into four grades: the most suitable,suitable,sub-suitable and unsuitable,for the study area 20%, 30%, 40% and 10% of respectively.
