宁波市地下空间开发地质环境适宜性评价
|
摘要
地下空间开发地质环境适宜性评价对于科学合理地开发利用城市地下空间资源具有重要作用。通过研究宁波市地质环境条件,从水文地质条件、工程地质条件和环境地质问题等3个方面选取了9个评价指标。运用层次分析法(AHP)构建地质环境适宜性评价指标体系,通过GIS软件空间叠加分析功能自动划分评价单元,采用模糊综合评判法进行地下空间开发地质环境适宜性评价。评价结果表明,宁波市地下空间开发的地质环境适宜性划分为4个等级:适宜(Ⅰ级)、适宜性较好(Ⅱ级)、适宜性较差(Ⅲ级)和适宜性差(Ⅳ级),其中浅层地下空间开发地质环境适宜性以Ⅰ~Ⅱ级为主(占比57%),中层地下空间开发地质环境适宜性以Ⅲ~Ⅳ级为主(占比58%)。
Geological environment suitability assessment of underground space development plays an important role in scientific and rational development and utilization of urban underground space resources. In the research of geological environmental conditions of Ningbo city,9 evaluation indexes are selected from the 3 aspect of hydrogeological condition,engineering geological condition and environmental geological problems. AHP method is adopted to set up geological environment suitability evaluation index system,and evaluation unit is automatically divided by the spatial overlay analysis of GIS software. Underground space development and geological environment suitability assessment is conducted by a fuzzy comprehensive evaluation method. The results show that, the geological environment suitability of underground space development in Ningbo can be divided into four grades: suitable( grade Ⅰ),sub-suitable( grade Ⅱ),generally suitable( grade Ⅲ) and poor suitability( grade Ⅳ). Geological environment suitability of shallow underground space is mainly Ⅰ~Ⅱ grade( accounting for 57%),while that of middle underground space development is mainly Ⅲ ~ Ⅳ grade( accounting for 58%).
