摘要
针对土坝的溃坝失事 ,建立了逐渐溃坝和瞬时溃坝两种数学模型 ,在论述它们各自的机理后 ,结合实例验证其实用性 ,并对其各自特点分别加以分析和比较 ,从而为防汛部门的防洪预报提供科学依据 .
The two mathematical models for earth dam break, a gradual dam break model due to overtopping and an instantaneous dam break model under some unknown urgent reasons, are set up. Through analyzing the two models' mechanisms and taking an actual example to use these models, it is verified that the two models are available. The characteristics of the two models are analyzed and compared each other. Thus, it provides a scientific basis for flood control and forecast.
