盾构隧道衬砌CAD软件的设计及应用

Design and applications of CAD software for shield tunnel lining

基于荷载-结构法并采用面向对象的设计方法,介绍了盾构隧道衬砌计算机辅助设计(GeoFBA)软件编制的理论依据、软件的适用范围及特点。软件考虑了各种可能的线性和非线性模式以及规范验算方法,实现了计算的图形化输入,适用于管片通缝和错逢拼装计算。该软件已经得到了广泛的应用,为工程设计人员和科研人员提供了有力的工具,极大地提高了设计人员的生产效率。

Based on the load-structure theory and using the object-oriented programming method, the theoretic basis of CAD software (GeoFBA) for shield tunnel lining is described and its usage and feature are also expounded. The software provides the various possible linear and nonlinear models as well as verification for segment design specification, and is suitable for two segment assembling types with the straight joint and the staggered joint. The software has been used widely in practice, which is a powerful tool to designers and researchers, and enhances greatly the productivity of designers.
