摘要
拱坝是重要的高坝坝型,体形复杂,在横纵和竖直方向的剖面均不相同。拱坝的BIM建模、浇筑仓建模和施工单元体形提取等任务涉及的体形参数多、分块条件繁杂、数据量大。以数字孪生技术为基础应用框架,基于CATIA二次开发,提出了坝体参数化建模、施工分块建模及其体形参数提取方法。在分析坝体施工单元参数化逻辑的基础上,建立坝体模型剖切方案,利用CATIA Automation API接口,在C#编程环境下实现拱坝参数化建模以及模型剖切与施工单元构建。模型能够获取施工单元的表面积、体积与角点空间坐标等属性参数,并可依据施工期工程管理需求动态更新,为复杂拱坝模型施工单元剖切、体形参数分析提供了高效易用的工具,同时对坝体施工进度和强度仿真提供数据和模型支持。
The arch dam is an important dam type among high dams with complex geometry,having different sections in the vertical direction and the horizontal direction.Tasks such as arch dam BIM modeling,pouring bin modeling and construction unit shape extraction involve many shape parameters,complex block conditions,and large amounts of data.Based on the secondary development of CATIA,this paper puts forward the method of parametric modeling of dam body,construction block modeling and shape parameter extraction.Based on an analysis of the parametric logic of the dam construction unit,this paper draws up the dam model sectioning plan and uses the CATIA Automation API interface to implement the arch dam parametric modeling,model sectioning and construction unit construction in the C#programming environment.As a result,attribute parameters such as the surface area,volume and corner space coordinates of the construction unit can be dynamically updated according to the needs of project management during the construction period,which can help predict the construction progress and strength of the dam and guide the construction in a scientific and orderly manner.It also provides an efficient and easy-to-use tool for sectioning complex arch dam model construction units and shape parameter analysis.
