基于已有堆石坝研究的理论分析和模型试验成果,综合水库调洪演算、溃口泥沙石料冲刷侵蚀计算和面板折断力学分析,构建了面板堆石坝漫顶溃口流量过程计算模型,以某面板堆石坝水库为例进行溃坝计算,并与其他溃坝计算结果做了对比。结果表明,该模型合理,计算精度较高,可为类似堆石坝的溃坝后果评估提供参考。 Based on the theoretical analysis and model test results of the existing rockfill dam, the reservoir flood regulation calculation, the erosion and erosion analysis of the sluice stone and the fracture mechanics analysis of the panel are established. As an example, the dam rockfill dam is calculated and compared with other dam failure results. The results show that the model is reasonable and the calculation accuracy is high, which can provide reference for the dam failure assessment of similar rockfill dam.
