为获得较合理的溃口流量过程线,从混凝土坝溃决的基本特点出发,假定其溃决过程为以坝基中心线为轴,坝体整体向后倾倒。对该溃决方式进行水动力分析,得到混凝土坝倾倒过程的溃口流量计算公式,并以此计算公式结合概化典型流量过程线法得到了新的溃口流量计算方法。以某工程为例,得出该计算方法与经典的混凝土坝瞬溃计算方法所得溃口流量过程线整体一致,但开始阶段更符合实际情况。新的溃口流量计算方法可为类似工程的大坝溃口流量分析提供参考。
In order to obtain a reasonable course of the breach discharge flow, starting from the basic characteristics of the concrete dam rupture, the collapse process is assumed to be based on the center line of the dam foundation, and the dam body is toppled backwards as a whole. The collapse of the collapse of the hydrodynamic analysis of the process of concrete dumped dump collapse flow calculation formula, and combined with the generalized typical flow process line method obtained a new calculation method of fault flow. Taking a project as an example, we conclude that this calculation method is consistent with the process curve of collapse flow rate obtained by the classical method of instantaneous collapse of concrete dam, but the initial stage is more in line with the actual situation. The new calculation method of the breach flow can provide a reference for the dam breach flow analysis of similar projects.
