摘要
基于元胞自动机理论,结合土石坝实际状况,模拟了导致土石坝溃决的主要要素,建立了土石坝溃决演化模型,并以大洼水库为例,采用该模型模拟了漫顶溃决和渗流破坏引起的土石坝溃决。结果表明,模拟结果与现场试验结果吻合较好。
Based on cellular automaton theory and actual condition of earth-rockfill dam, this paper simulates principal elements which cause the dam break. And then an evolution model of earth-rockfill dam break is established. Taking the Dawa Reservoir for an example, earth-rockfill dam break caused by overtopping and seepage failure is simulated with the proposed model. The results show that the simulation is accord with the field test.
