摘　　要：城市地下空间地质环境条件适宜性评价对于有效利用地下空间至关重要.该研究以深圳市南山区深圳湾超级总部基地片区为例,构建了以地质环境条件为基础,考虑片区既有地面、地下建筑开发现状的地下空间地质环境条件适宜性三维评价体系.该体系基于三维数据的特点和其他实际要求,体系构建主要包含4个步骤:1)利用多源地质数据的隐式三维地质建模方法建立三维地质模型;2)根据现有数据考虑当地地质条件,建立三维评价指标体系;3)利用三维空间分析方法,从三维地质模型中构建三维评价数据集;4)使用多级指数叠加法进行综合评价.结果表明,深圳湾超级总部基地片区地质环境条件适宜性总体较好,深层地质环境条件适宜性优于中层和浅层.该评价体系能够有效地整合二维和三维地质信息,给出更合理的评价结果,并提高结果深度方向上的分辨率.评价结果可以为深圳湾超级总部基地及其他重点片区地下空间规划利用提供有价值的参考.The evaluation of the suitability of geological environmental conditions of urban underground space is crucial for the effective utilization of underground space.Taking Shenzhen Bay Super Headquarters Base Area in Nanshan District of Shenzhen City as an example,a three-dimensional evaluation system of the suitability of geological and environmental conditions of underground space was constructed based on geological environmental conditions and considering the current development status of existing underground buildings in the area.The system is based on the characteristics of three-dimensional data and other practical requirements,and the construction of the system mainly consists of four steps:1)establishing a three-dimensional geological model by using the implicit three-dimensional geological modeling method of multi-source geological data;2)establishing a three-dimensional evaluation index system based on the existing data considering the local geological conditions;3)constructing a three-dimensional evaluation dataset from the three-dimensional geological model by using three-dimensional spatial analysis method;4)conducting a comprehensive evaluation by using the multilevel index superposition method for comprehensive evaluation.The results show that the suitability of the geological environmental conditions in the Shenzhen Bay Super Headquarters Base Area is generally better,and the suitability of the deep geological environmental conditions is better than that of the middle and shallow layers.The evaluation system is able to effectively integrate 2D and 3D geological information,give more reasonable evaluation results,and improve the resolution of the results in the depth direction.The evaluation results would provide valuable references for the planning and utilization of underground space in Shenzhen Bay Super Headquarters Base and other key areas.
