摘要
以桂林市规划中心城区为例,选取了12个影响岩溶地区地下空间开发利用的地质环境因素(地貌类型、地下水富水性、地下水位埋深、地下河对地下空间开发的影响程度、土体厚度、土体地基适宜性、岩体结构、岩溶塌陷易发程度、岩溶发育程度、断裂构造、特殊性土发育程度、人类工程活动强度),利用地质环境要素通过专家-层次分析法建立了岩溶地区地下空间开发适宜性评价指标体系和评价方法,并通过MapGIS软件实现可视化。依据预测分区指标计算,将研究区浅层地下空间资源开发利用适宜性划分为:适宜性好(Ⅰ)区的面积为34.43 km^2;较好(Ⅱ)区412.34 km^2;较差(Ⅲ)区397.71 km^2;差(Ⅳ)区35.52 km^2。
Taking the planning central urban area of Guilin as an example, 12 geological and environmental factors affecting the development and utilization of underground space in karst areas were selected(Geomorphic types, groundwater enrichment, groundwater level, the impact of underground rivers on underground space development, soil thickness, foundation suitability, rock mass structure, karst collapse susceptibility, the degree of karst development, fracture structure, special soil development, human engineering activities intensity).The evaluation index system and method of suitability for underground space development in karst area were established through the expert -analytic method using geological environment elements, and visualization is realized through MapGIS software. According to the predicted zoning index, the suitability of shallow underground space resources development and utilization in the study area is divided.The best suitability area is 32.59 km 2.The sub-level suitability area is 412.34 km 2.The poor suitability area is 397.71 km 2.And the even-worse area is 35.52 km^2.
