摘　　要：为解决大型岩土工程三维数值模拟过程中地质模型复杂、不同软件网格兼容性差、剖分效率低的难题,基于3DMine矿业工程软件和Rhinoceros软件平台,采用NUBRS曲面建模技术快速构建通用三维地质模型,并通过Hypermesh软件进行快速网格剖分;开发了Hypermesh通用数值网格与FLAC3D、ANSYS、ABAQUS等数值计算网格间的转换程序。通过某露天矿边坡三维地质模型和数值网格构建的实例,验证了该方法的可靠性和高效性。In order to solve the problems of complex geological model,poor mesh compatibility and low mesh generation efficiency in three-dimensional numerical simulation of large geotechnical engineering,a general three-dimensional geological model was constructed by NUBRS surface modeling technology based on 3DMine mining engineering software and Rhinoceros software platform,and the mesh generation was carried out by Hypermesh software.The conversion program between the general numerical grid division of Hypermesh and the numerical calculation grid of FLAC3D,ANSYS and ABAQUS was developed.The reliability and efficiency of the method are verified by an example of three-dimensional geological model and numerical grid construction of an open pit slope.
