基于Revit二次开发的水利工程算量应用研究

Studies and Implementations of Hydropower and Water Conservation Quantity Calculations Based on Revit Secondary Development

为提高水利水电工程异形结构工程量计算效率和成果可靠度,基于Revit和.Net框架,利用RevitAPI采用C#语言进行二次开发,形成数据库交互、构件编码、构件目录树、链接模型处理和数据导出等功能模块,用于从BIM模型可视化快速提取工程量至外部数据库并输出工程量明细。将程序用于拟建重力坝工程量的计算实践中,实现了各坝段分区混凝土方量的快速输出,经与传统方法相比,精度满足要求,为水利水电工程BIM正向设计奠定了基础。

In order to increase the effectiveness of amount computation and the dependability of the outcomes of specially-shaped structures in water conservation and hydropower projects.Functional modules like database interaction,component coding,component directory tree,link model processing,and data export are formed using Net Frameworks,the Revit API,and the C#language for secondary development.These modules are used to quickly extract engineering quantities from BIM model visualization to external databases and output bills of quantities.When compared to the previous method,the program's rapid output of concrete quantity for each dam section meets the required accuracy when employed in the engineering quantity calculation practice of the proposed gravity dam.This approach lays the groundwork for the future BIM design of hydropower and water conservation projects while significantly increasing the efficiency and accuracy of hydraulic structural calculations.
