地质灾害治理工程三维辅助设计应用探索

Application of Three-dimensional Computer Aided Design for Geological Disaster Prevention

传统的地质灾害治理设计成果图件是经过笛卡尔投影几何转换的平面、立面、剖面图,容易导致认知的歧异和结果误差,对于地质灾害治理项目的设计、施工、管理均会产生不良的影响。基于Sketch Up软件的三维辅助设计,是对传统地质灾害治理设计的良好补充和突破。Sketch Up软件具有强大的建模功能、优秀的互动界面、良好的联系通道等诸多优点。三维辅助设计在设计效果的直观表达、工程量的准确计算、三维大样图的制作、三维动态演示等许多方面能够得到很好的应用。这种辅助设计方法在地质灾害治理项目上具有良好的实用价值和应用前景。

Traditional design drawing of geological disasters include plane, elevation, section by Descartes projection. The drawing can easily lead to cognitive differences and error, which have adverse effects on design, construction, management of geological disaster prevention project. Three-dimensional computer aided design based on Sketch Up software is a good supplement and breakthrough to the traditional geological disaster prevention project. Sketch Up have a big advantage in modeling function, interactive interface, contact channel. Three-dimensional computer aided design have many applications in visual design effect, the accurate calculation of engineering quantity, three-dimensional detail drawing,three-dimensional dynamic demonstration etc. The aided design method have a good practical value and application prospect in geological disaster prevention project.
