铁路路基岩溶动态设计软件的开发与应用

Development and Application of Software for dynamic Design of Railway Subgrade Karst

岩溶发育具有隐蔽性、复杂性的特点,有限的地质勘探难以准确、完整的揭示其发育特征。目前高速铁路项目为确保整治效果及运营安全,一般采用动态设计整治方案,利用施工钻孔,探灌结合,进一步更全面的验证、揭示岩溶特征。动态设计通常采用交互式绘图平台AutoCAD,其功能强大,易于操作,但其功能具有普适性,不能很好得满足岩溶整治动态设计的特定需求,故导致了设计工作量大、效率低、繁琐易出错的难题。针对上述问题,本文作者以C#.net为开发工具对AutoCAD进行了二次开发,实现了导入路基断面数据、定义整治原则、先期工程平断面自动设计、后期工程平断面自动设计、数量计算、生成设计说明及图面布置等功能。软件已应用于多个项目的实际生产,大幅提高了设计效率,同时提高了设计的精准性。

Due to the concealment and complexity of Karst development,it is difficult to disclose accurately and completely its development characteristics by limited geological exploration. To ensure the effectiveness of treatment and safety of operation,the solution of dynamic design is usually adopted in the high speed railway project. With the help of the construction drilling hole and in combination with exploration and grouting,the karst features are more completely disclosed. The interactive drawing platform AutoCAD characterized by powerful function and simple operation is usually used for dynamic design. But the universality of Auto CAD cannot meet the specific need of dynamic design of Karst treatment,which causes heavy design workload,low efficiency and tedious and prone problems. In view of such problems,taking C #. net as development tool in Auto CAD environment,a new software is developed,it has the functions of introduction of subgrade section data,definition of design principles,automatic plan and section design of phase I and phase II of the project,calculation of quantities,generation of design notes,and drawing arrangement. The software has been applied in multiple projects. Benefited from this software,the design efficiency is substantially increased and the design accuracy is improved.
