| 中文摘要: |
| 工程区域地质条件是影响地下洞室群布置最主要的因素。本文基于NURBS技术和地质结构单元实体分割理论，建立了工程地质三维整体模型。在该模型的支持下，结合参数化建模得到的地下洞室群三维几何模型，进行了模拟开挖和地下建筑物特征部位的地质三维可视化分析。将该方法应用于西南某大型水电工程中，在综合考虑各种约束性地质因素的条件下，通过多方案的地质综合评价，在地质构造上实现了地下洞室群布置的快速优化，为最终方案的确定提供了重要的技术支持。 |
| 英文摘要: |
| Based on the NURBS technique and the theory of partition for geologic body, the 3 D engineering geologic model for underground structures is established. With the support of this model and combined with the geometric model of underground structure group established from parameterized modeling, the 3-D visualized geological analysis on excavation process and characteristics of specific locations of structures can be carried out. This method is applied to analyze the underground structures of a typical large scale hydropower project. The quick optimization of the project layout is achieved according to the restrictive conditions of the geological factors and comprehensive assessment of various schemes based on the proposed method. |
