高土石坝施工系统可视化仿真与应用研究

Visualization simulation for embankment dam construction and its application

就土石坝施工中的土石方调配与坝体施工组织设计优选进行了讨论分析. 对于前者通过建立调配问题的数学模型采用线性规划的方法进行优化求解;而对于后者,采用循环网络仿真技术对土石坝的整个施工过程进行仿真. 基于此,提出了土石坝施工系统可视化仿真的概念,充分考虑以上两者之间相互影响与制约的关系,将两者有机地统一起来,并以GIS可视化技术为基础,将其实现过程以可视化的形式输出,为工程设计人员形象、直观、快速地把握施工过程提供有力工具. 某工程实例的详细应用证明了此方法的有效性,从而为工程施工组织可视化辅助设计提供一种新途径与新方法.

Two main problems in embankment dam construction, earthwork allocation and construction organization plan, are analyzed firstly in this paper. For the former, Linear programming is used to solve the built mathematics model. While for the later, Cycle Operation Network is adopted to simulate the whole construction process. Based on these the conception of visualization simulation for embankment dam construction is proposed. Furthermore, GIS technique is utilized to visualize the results of the two problems which are otherwise difficult to be understood by static results described in texts. A case study in a embankment dam construction project is presented. The detailed results show that it is a potential tool to master the construction process for engineering designers, and also it is a new method and path for Visual Computer Aided Design (VCAD) of engineering construction plan .
