基于三维实体模型的拱坝浇筑仿真研究

STUDY ON THE SIMULATION MODELING OF ARCH DAM CONSTRUCTION BASED ON SOLID MODEL

针对已有的混凝土拱坝浇筑仿真软件的特点,利用.NET平台对AutoCAD二次开发技术,将AutoCAD软件三维建模便利性与离散事件仿真过程结合,构造与施工信息相结合的三维模型,将AutoCAD三维模型作为仿真系统的大坝形体模型,从而实现拱坝仿真计算形体模型与AutoCAD三维模型的统一,同时实现仿真结果三维可视化。最后利用某工程模拟对系统进行了验证。

By analyzing the characteristics of existed concrete arch dam construction simulation software,we developed a system that utilizes the secondary development method of AutoCAD based on C#.NET.It integrates the 3D modeling and discrete-event simulation as well as creates 3D models that combined with construction information.The 3D model can be used as arch dam body model of simulation.And the system also realized 3 D visualization the simulation result.At last,the simulation platform is applied to a project instance,which verifies the validity of it.
