摘要
土石坝是世界大坝工程建设中应用最为广泛和发展最快的一种坝型。溃坝是土石坝面临的最为关键的工程问题之一。本文结合某工程实例,基于BIM技术进行土石坝溃坝仿真模拟。采用3ds MAX软件建立大坝模型,基于Rayfire技术模拟大坝溃坝发展过程,运用Realflow软件模拟溃坝洪水演进过程。通过BIM技术集成大坝建模、溃坝发展和溃坝洪水模拟方法,模拟大坝实际溃决过程,获取溃坝淹没范围、深度、演进时间等重要溃坝参数。本文研究可以为在建或已建土石坝溃坝的风险分析和评估提供一定的技术支撑。
The earth-rock dam is the most widely used and fastest-developing dam type in the construction of world dam projects. Dam failure is one of the most critical engineering problems faced by earth-rock dams. This paper combines a project example to simulate the earth-rock dam breakout based on BIM technology. The dam model was established by using3 ds MAX software. The development process of dam failure was simulated based on Rayfire technology, and Realflow software was used to simulate the dam flood evolution process. Through BIM technology integrated dam modeling, dam failure development and dam break flood simulation method, the actual dam break process is simulated, and important dam break parameters such as dam break submergence range, depth and evolution time are obtained. This study can provide some technical support for risk analysis and assessment of dam breaks in construction or built earth and rock dams.
