工程地质条件是连拱隧道工程设计和施工必须重点考虑的因素。根据实际连拱隧洞工程的需要,采用三维地质建模技术建立起接近真实形态的工程地质三维模型,并以该模型为基础,设计了三维地质可视化分析函数,实现一系列的地质信息三维可视化剖切分析。该技术方法在隧道工程中的应用表明,地质三维可视化建模与分析技术可以满足地下隧道工程的地质分析需要,有效地提高工程设计和施工的效率与水平。
Engineering geological conditions are the key factors in the design and construction of multi-arch tunnel. According to the needs of the actual arch tunnel project, the three-dimensional geological modeling technology is used to establish a nearly three-dimensional model of engineering geology. Based on the model, a three-dimensional geological visualization analysis function is designed to realize a series of three-dimensional visualization of geological information Cut analysis. The application of the technique in tunnel engineering shows that the geological three-dimensional visualization modeling and analysis technology can meet the geological analysis needs of underground tunnel engineering and effectively improve the efficiency and level of engineering design and construction.
