摘    要:基于面向对象技术、可视化技术和数据库管理技术集成开发了铁路路基加固设计系统,系统由数据库管理、常规设计计算、有限元计算和反馈分析4个模块组成,对计算过程中的大量数据信息进行分类管理;有限元法计算与分层总和法互补,能实现天然地基和复合地基的模拟计算,解决一些常规设计计算方法难以解决的问题,提高计算精度;基于神经网络和有限元的反馈分析既可实现路基土层力学参数的反演,提高铁路路基加固设计计算的精确性,亦可实现对路基固结沉降的预报。应用结果表明,铁路路基加固设计系统改进了路基加固设计的常规计算模式,整个计算过程通过用户和界面交互完成,可保证路基加固设计的效率和质量,具有较强的实用性。

关 键 词:铁路路基  加固设计  面向对象  可视化  数据库管理

Abstract:In this study,a railway subgrade strengthening design system was developed based on object-oriented,visualization,and database management technology.The system consists of four modules(the database management module,the conventional design calculation module,the finite element calculation module,and the feedback analysis module) and can be used to effectively classify and manage the mass data during the calculation process.The finite element method complemented the layer-wise summation method in this study.These two methods can realize simulations of the natural foundation and composite foundation,solve problems that cannot be settled by conventional methods,and improve calculation accuracy.The feedback analysis based on the neural network method and the finite element method can not only achieve the inversion of the subgrade soil mechanic parameters and improve the calculation accuracy of the railway subgrade reinforcement design,but also predict the consolidation settlement of the subgrade.The application results show that the railway subgrade design system improves the conventional calculation model.The whole calculation process is completed by the user-computer interface which can guarantee the efficiency and quality of the subgrade reinforcement design.The results also indicate that the system has great practicality.
Keywords:railway subgrade  reinforcement design  object-oriented  visualization  database management
