摘要:水利工程具有很强的系统性和综合性。水工建筑物的结构复杂、形态各异，利用数字模型进行虚拟建造，提前优化设计，并最终形成实体建筑物，是目前水利工程结构体型设计过程中的主要方法。在凯乐塔水利枢纽工程建设过程中，采用参数化模型快速进行建筑物优化设计，将构件模板、参数以及其他常用命令开放的API进行二次开发，并将参数集成到可编辑的文档，并实现模型和文档的双向驱动，根据需要调取模板库中符合设计要求的模板，程序自动关联协调不同模板间的参数值，一键生成所需的模型。将已设计完成的模型生成实例库，可为相似工程提供参考。同时，采用不同细节深度的模型，在协同平台上对模型进行版本管理，采用BIM技术作为模型和信息的载体，根据现场施工需要进行深化设计，提取模型及数据，进行技术、现场、进度、成本管理，并最终形成竣工模型。在竣工模型上添加设备运行维护等信息，用于运行维护管理。

Abstract: Water conservancy projects are usually complicated and comprehensive.In that the hydraulic buildings are always complex in structure and different in shape, using virtual construction based on digital model and optimizing design in advance for the final hydraulic building is the most popular method in the design process of hydraulic structure. During the construction process of the Kaleta Hydropower Station Project, the parametric model is used to optimize the building design rapidly.Through a secondary development on those component templates, parameters and frequently-used API, we can integrate the parameters into editable documents, thus realizing the bidirectional drive between model and documentation.Furthermore, we can retrieve the template in line with the design requirements from library as needed.The program can automatically associate different parameters to the model, and generate the required model in one step.An example library collecting all well-designed models can provide reference for similar project.Based on models with different depth of detail, the collaborative platform can also realize the version control of models and deepening design as needed on construction site.Also, models and data can be extracted in assisting technical, site, schedule and cost management, which produces the final completion model.Last but not least, the completion model can be integrated with operation and maintenance information to facilitate the operation maintenance management.
