| 摘 要： | 城市地下空间开发地质环境质量评价可为城市地下空间规划和工程建设提供重要决策支持。该文以合肥市滨湖新区为例,构建城市地下空间开发地质环境质量三维评价方法:利用三维隐式建模方法融合多源数据进行三维地质建模,从工程地质、水文地质、地质构造和不良地质体等方面构建三维评价模型,利用三维距离场分析、三维空间统计分析等方法对三维评价因子进行分析、提取,最后基于确权和综合评价方法得到地下空间开发地质环境质量三维综合评价结果。实例研究表明:该方法能够显著提高评价结果的深度方向分辨率,相关成果可为城市地下空间精细规划及可持续开发利用提供方法参考。

| Abstract: | The geological environment quality assessment of underground space development can provide important decision sup-port for urban underground space planning and engineering construction.This paper takes Binhu New District of Hefei City as an example to construct a three-dimensional evaluation method process of geological environment quality for urban underground space development.The 3D implicit modeling method is used to fuse multisource data for 3D geological modeling.Then the 3D evaluation models are constructed from engineering geology,hydrogeology,geological structure and unfavorable geological bodies,and the threedimensional evaluation factors are obtained by 3D distance field analysis and 3D spatial statistical analysis,etc.Finally,threedimensional comprehensive evaluation results of geological environment quality of underground space develop-ment are obtained based on weight determination of evaluation factors and comprehensive evaluation method.Case study shows that the method proposed in the paper has good practicability,can significantly improve the resolution of the evaluation results in the depth direction,and the related results can provide a more reasonable and refined method reference for the fine planning and sustainable development of urban underg round space. |
