摘要
基于过水围堰下游护坡稳定性分析、实际观测资料和模型试验的研究成果,在分析土石过水围堰溢流工况的基础上,建立了溢洪堰面抗冲刷的风险率模型,提出了风险率的Monte-Carlo计算方法。通过模型试验的对比论证分析,说明溢流风险率计算模型和计算方法是可行的、有效的,为土石过水围堰堰体下游护坡结构和消能防冲设计提供了理论依据。
Based on former results, actual observational data and model tests of downstream slope protection stability for overflow cofferdam and confirming the worst overflow, risk model of overflow is established and MonteCarlo method is put forward. Compared with model tests, it shows validity of computing model and method,which offers theoretic basis for downstream protection slope structure design and energy dissipation and erosion.
