摘要
随着我国城市化的快速发展,城市地上地下一体化规划和建设的需求逐渐增大,城市三维地质建模的作用日益重要。以武汉市为例,针对该城市地质条件复杂的情况,运用一种分区交互式建模方法。该方法通过地层剖面数据与水平方向的中断面或地质图所形成的网格作为最小单位,结合断层等特殊地质情况,手动构建地质体,并最终完成整个区域的三维地质模型建立。论文罗列了在模型建立过程中出现的问题,并给出了具体建议。所建三维地质模型已通过野外验证,表明本方法能够很好地应用于城市三维地质建模。
With the rapid development of urbanization in China,the need for urban aboveground and underground integrated planning and construction is increasing gradually,and the role of urban 3D geological modelingbecomes more and more important.According to the complex geological conditions in Wuhan,apartition interactive modeling method is proposed in this paper.The method takes the gridcomposed of stratigraphic profile dataand the horizontal middle cross-section or geological map asthe smallest unit,and establishes3D geological model of entire region combined with the special geological conditions such as fault to construct geological body manually.This paper lists the problems in the process of model building and gives some suggestions.The3D geological model has been validated in the field, which shows that this method can be well applied to urban 3D geological modeling.
