堆石坝施工组织的计算机辅助设计研究

高堆石坝施工过程复杂，影响施工的随机因素众多，传统的设计方法很难准确地得到施工组织设计中一些重要的参数。以现有循环网络仿真技术为基础，利用GIS的三维可视化技术，通过对堆石坝施工过程的系统分析与研究，实现了堆石坝施工组织的计算机辅助设计，得到了合理的施工参数，形象地描述了堆石坝施工过程复杂的时空逻辑关系。为此，编制了仿真计算程序，并在某高堆石坝施工中应用。其详尽的仿真成果证明了仿真软件是制定切实可行的大坝施工组织方案、预测工程未来进展以及进行施工现场的实时控制与管理的有效手段。

Study on the computer-aided design for the construction arrangement of rock-fill dam

For its complexity and randomness, it is hard to obtain accurately som e important parameters in the design of construction arrangement of rock-fill da m with conventional method.Based on the technique of Cycle Operation Network and GIS, through the analysising and studying on the construction processes of rock-fill dam, we realized the computer-aided design for the construction processes of rock-fill got the reasonable parameters and visual expressed the complex time and space relations in construction processes. Based on the ideas, the simulati on software for construction of rock-fill dam is programmed. The application in an actual rock-fill dam shows the validity and efficiency of the method. And als o with it the engineer can determine the construction planning reasonably, predi ct the construction progress precisely, and control the construction quality in site.
