Abstract：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.
