【摘要】 堤防工程具有线路长、地形地质条件变化大、工程措施多变等特点,利用传统二维方法来完成设计会十分繁杂,难以提高工作效率。三维设计是水利工程勘测设计发展的必然趋势,基于CATIA软件进行了堤防工程三维设计的探索研究。首先介绍了利用CATIA软件进行堤防工程三维设计的基本思路与技巧,并以洪湖东分块蓄滞洪区蓄洪工程的腰口隔堤为例进行了地质三维建模、堤防参数化模板构建、堤防三维设计建模;随后基于三维勘测设计模型进行了方案比选、工程量计算、二维出图等初步工程应用。结果表明:相比于传统二维设计,基于CATIA的三维设计可以显著提高工作效率,便于直观表达设计意图,在堤防工程等长线路工程中的优势十分明显,具有广阔的应用前景。更多还原

【Abstract】 The levee project has the characteristics of long line, great changes in topographic and geological conditions, various engineering measures and so on. So it is very complicated to use the traditional two-dimensional method to complete the design work and difficult to improve the work efficiency. 3 D design is the inevitable trend of survey and design for water conservancy project. This paper explores and studies the 3 D design of levee engineering by CATIA software. Firstly, the basic ideas and skills of 3 D design of dike engineering by using CATIA software are introduced. Taking Yaokou embankment of flood storage and detention area in Honghu East Block as an example, geological 3 D modeling, dike parametric formwork construction and dike 3 D design modeling were carried out. Then, based on the three-dimensional survey and design model, the scheme comparison and selection, engineering quantity calculation, two-dimensional drawing and so on were carried out. The results show that compared with the traditional two-dimensional design, the three-dimensional design by CATIA can significantly improve the working efficiency and express the design intention intuitively. It has obvious advantages in levee engineering and other long line projects, and has a broad application prospect.更多还原
