温州市规划区地下空间开发地质环境适宜性评价

Geological environment suitability evaluation of underground space development in Wenzhou planning area

地下空间开发地质环境适宜性评价可为城市科学规划建设提供有力的技术支撑与参考依据,具有非常重要的意义。结合温州市规划区的地质环境特点,从工程地质条件、水文和水文地质条件、地质环境条件、地面和地下条件4个方面选取了14个评价指标。采用层次分析法(AHP)计算各评价指标的权重,通过GIS软件划分评价单元进行人机交互分析,将运用模糊综合评价法计算得到的结果反映到适宜性评价成果图上。评价结果表明,浅层地下空间开发地质环境适宜性好的面积约占60.8%,适宜性较好的约占2.6%,适宜性一般的约占30.6%,适宜性差的约占6.0%;中层地下空间开发地质环境适宜性好的面积约占32.2%,适宜性较好的约占39.2%,适宜性一般的约占20.4%,适宜性差的约占8.3%。

The geological environment suitability evaluation of underground space development can provide strong technical support and reference basis for urban scientific planning and construction,which is of great significance.Combined with the geological environment characteristics of Wenzhou planning area,14 evaluation indexes are selected from 4 aspects:engineering geological conditions,hydrological and hydrogeological conditions,geological environment conditions,ground and underground conditions.Analytic hierarchy process(AHP)is used to calculate the weight of each evaluation index,and the evaluation unit is divided by GIS software for human-computer interaction analysis.The results calculated by fuzzy comprehensive evaluation method are reflected in the suitability evaluation result map.The evaluation results show that,About 60.8%of the shallow underground space is suitable for development,2.6%of the shallow underground space is sub-suitable,30.6%of the shallow underground space is generally suitable,and 6.0%of the shallow underground space is poor suitability;About 32.2%of the middle underground space is suitable for development,39.2%of the middle underground space is sub-suitable,20.4%of the middle underground space is generally suitable,and 8.3%of the middle underground space is poor suitability.
