中文摘要：
利用专业三维地质建模软件GOCAD（Geological Object Computer Aided Design）,通过野外实测离散的工程勘测数据拟合和插值，建立了该边坡（含地形、地层分界线等信息）的三维地质模型，把地质结构信息通过三维可视化具体体现，并且可以任意切割剖面加深对地质结构的认识。由于三维地质模型的建立，一方面为地质工程人员进一步分析研究桥基边坡稳定性及数值模拟分析计算提供一种新的手段和方法，另一方面为非地质工程人员对边坡三维地质结构直观认识均具重要工程实际意义。
英文摘要：
The paper makes use of the professional three-dimensional geological modeling software named GOCAD （Geological Object Computer Aided Design）, and on the base of the date of field--surveyed it interpolates and simulates the landform, geo- logic layers, then builds up the three-dimensional geologic modeling of one talus slope. Meanwhile it shows the geological structure of underground by the three--dimensional visualization and engineers can discretionarily incise sections to get an in- depth understanding of the geological structure. Through the foundation of the three-dimensional modeling, it provides a kind of new method for personnel engaging in the geologic engineering, which can help the analysis of the stability of a talus slope and numerical simulation. On the other it let personnel who do not engage in the geologic engineering have a intuitive feel and recognition to the three-dimensional geological structure.
