根据岩石力学有限元方法的内在特性，本文采用面向对象的程序设计方法实现了岩石力学有限元方法前处理可视化技术。 首先，本文根据有限元前处理过程中数据类型多、数据量大的特点，建立了适合有限元用户的可视化界面，减轻了用户的记忆负担。岩石力学有限元前处理可视化方法中有一个难点问题和一个重点问题。难点是如何实现有限元网格快速自动剖分，同时如何保证生成的网格的质量。重点是岩土工程施工的可视化模拟，即如何在前台处理上实现施工信息的可视化、形象化，而在后台处理上形成准确的施工数据。本文成功地解决了这两个难点和重点。另外，本文还顺利实现了有限元前处理中其他参数如材料、边界条件、荷栽的可视化输入，从而从很大程度上减少了用户的建模时间。 数据管理方式的优劣性是有限元前、后处理效果上的一个决定性因素，它既影响着有限元可视化的程度，也影响着有限元方法的发展与应用。本文采取先进的ODBC数据库管理方式代替了传统的文件管理方式，并给出了具体的有限元前后处理中所需要的各种数据表格，同时概括说明了有限元与数据库的接口技术。实例表明，在有限元前后处理中采用数据库数据管理更趋近于科学性、先进性。 两个具体的实例说明，文中的有限元可视化方法是正确、可行的，同时其成果在岩土力学与工程中具有一定的应用、研究价值。 最后，本文指出了有限元前后处理中的部分发展趋势及难题，为以后的研究提供了一定的参考。

The technique of visualization in the Pre-Process of finite element method(FEM) has been accomplished in the way of object oriented programming in this paper, which is based on the intrinsic characteristics of geomechanics. First of all, a visual user interface is built up which is suited to FEM USER and is aimed to reduce the burden of user remembering according to the character of FEM that the type of its data is multiple, and the quantity of its data is great. There are one difficult subject and one important subject during the process of the visualization of FEM. The difficult one is how to generate meshes of FEM automatically and quickly and how to ensure their quality. The important one is the visual modeling of geotechnical construction, which also means how to portray the construction information more visually and lively before the scene, and how to get the information’s data accurately behind the scene. Both of the two subjects are achieved in this paper. The visual input of other parameters such as material, boundary condition, load, which are necessary to the pre-process of FEM ,is also accomplished perfectly. Therefore, the time of user building model is reduced largely. The degree of superiority of data management is a decisive factor for the effects of pre-process and post process of FEM, because it not only affects the extent of visualization of FEM, but also affects the development and application of FEM. The Open Data Base Connection(ODBC), which is one of the most advanced database management technique, is adopted as a substitute for traditional file management in this paper. Several database tables, which are indispensable to the pre-process and post process of FEM are applied, and the technique of interface of FEM and database is introduced generally in the paper. It is more scientific and superior to manage the Data of FEM in the way of ODBC shown by an example. Two detailed examples prove that the way of visualization in the paper is reasonable and practicable, and its achievement provides some value of application and research in the field of geomechanics and geotechnology. Finally, Some trends and hard nuts of the visualization are pointed out in this paper, which are references for the future research
