【摘要】：以往水利行业的工程设计多是采用传统二维CAD技术,与之相比,BIM(建筑信息模型)技术具有表达直观、纠错能力强、信息完备等优点。为克服传统设计技术图纸不易修改、表达效果抽象、工作效率低下等缺点,以实现适应斜心墙土石坝特点的水利信息化技术为目标,以CATIA为平台,结合某斜心墙土石坝工程,基于VB对CATIA进行二次开发,建立了参数化模型。同时,基于该模型可快速修改与更新的特性,完成了以填筑量为标准的坝轴线方案比选。最后,基于三维模型所提供的信息进行二次开发实现了多截面的坝坡稳定计算。实践证明,CATIA技术可代替传统设计方法实现信息化建模,也可更广泛实现工程建设全过程的分析计算、施工管理与运行管理工作,进一步提升行业管理水平。
[Abstract]:In the past, the engineering design of water conservancy industry mostly used the traditional two-dimensional CAD technology, compared with the BIM (building information model) technology has the advantages of intuitive expression, strong error-correcting ability, complete information and so on. In order to overcome the disadvantages of traditional design technical drawings, such as difficult to modify, abstract expression effect and low working efficiency, the aim of water conservancy information technology, which adapts to the characteristics of inclined core earth and rock dams, is to take CATIA as the platform, and to combine with a certain inclined core earth and rock dam project. Based on VB, the secondary development of CATIA is carried out, and the parameterized model is established. At the same time, based on the characteristics that the model can be quickly modified and updated, the selection of dam axis scheme based on filling quantity is completed. Finally, based on the information provided by the three-dimensional model, the stability calculation of multi-section dam slope is realized by secondary development. It has been proved by practice that CATIA technology can replace the traditional design method to realize information modeling, and can also widely realize the analysis and calculation of the whole process of engineering construction, construction management and operation management, and further improve the level of industry management.
