摘要
结合泰安市地下空间开发利用现状,分析了地质环境特征与地下工程建设和地下空间开发的相互影响机制。采用层次分析法,从工程地质条件、水文地质条件、环境地质问题和不良地质作用等方面建立了地下空间适宜性评价指标体系,构建分析模型;通过综合确定各指标的权重,以GIS软件空间叠加分析功能自动划分评价单元,对泰安市地下空间开发的地质环境适宜性进行了分区评价。同时,通过对各分区地质条件的说明对适宜性分区结果进行了分析和验证,以期为泰安市地下空间开发利用建设提供决策依据。
Combining with current situation of underground space development and utilization in Tai'an city,the interaction mechanism between geological environment characteristics,underground engineering construction and underground space development is analyzed.By using analytic hierarchy process(AHP),the evaluation index system of underground space suitability has been established from aspects of engineering geological conditions,hydrogeological conditions,environmental geological problems and adverse geological processes,and the analysis model has been constructed.Through determining the weight of each index comprehensively,the evaluation unit can be automatically divided by spatial superposition analysis function of GIS software to improve geological environment suitability of underground space development in Tai'an City.At the same time,through explanation of geological conditions of each division,the results of suitability zoning are analyzed and verified.
