Research And Development Of Highway Tunnel Lining Design System

The design of Geotechnical and Underground Engineering is based mainly on engineering analogy and secondly on theoretical calculation. To develop software that combines FEM calculation and design code meets the need of practical engineering design, and therefore is the tendency of developing computer aided engineering software.This paper is about software for highway tunnel lining design. The paper researches on practical requirements of lining design, and develops a lining design system based on GeoFBA2d software platform.1. The software framework and the corresponding developing plan are established. This paper improved the framework of GeoFBA2d software platform, but kernel calculation functions are from GeoFBA2d software platform.2. Encapsulating some kernel functions from GeoFBA2d software platform, including FEM calculation, pre-processing, and post-processing.3. Based on the new framework and these kernel functions, A detailed Object-Oriented design for this system is finished. Modules of parameterized design and Load-Structure calculation are completed.
