中文摘要：

现有的三维地质模拟技术没有考虑地质空间几何结构场与属性参数场之间的耦合关系,从而限制了计算机模拟结果的真实性和实用性。工程地质空间多场耦合构模问题已成为制约三维地质模拟技术深入发展应用的瓶颈。在综合国内外研究现状与发展趋势的基础上,提出了工程地质空间多场耦合构模的总体研究框架和基本工作流程,给出了研究过程中所遇到的主要科学问题的解决思路或实现方案,并通过实例说明地质体多场耦合模型在三维地质建模及可视化系统中初步实现后的效果。这些研究成果为建立一套完整的地质体多场耦合构模理论体系和方法体系奠定了基础,有助于推动工程地质数字化建模分析技术的深入应用。

英文摘要：

The coupling relationship between structure field and property parameters field in geological space is not considered in current technology of 3D geological modeling, and this situation limits the reliability and the practicality of the computer modeling. Multifield coupled modeling in engineering geological space has become a bottleneck that restricts the development and application of 3D geological modeling. Based on the review of the present situation and development trends in 3D geological modeling, the general research framework and the primary working procedure for multifield coupled modeling in engineering geological space are introduced; and solving means of related scientific problems on multifield coupled modeling are given. The visualization effect of the multifield coupled model is realized inside the 3D geological modeling and visualization system; and the practical effect of those methods is shown in a case study. This research lays a foundation to build the theory and method system for multifield coupled modeling of geological bodies; and also is helpful to promote the deepening application of digital modeling and analytic techniques for engineering geology.
