摘要
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 research results of theoretical analysis and model test in the field of rockfill dam,the calculation model of break breach overtopping flow for panel rockfill dam is established by integration of reservoir flood routing,erosion of dam break breach sediment and stone and panels fracture mechanics analysis.Taking a reservoir of panel rockfill dam for an example,compared results with other dam break model show that the proposed model is reasonable and it has high accuracy.The study result can provide reference for dam break consequences of similar rockfill dam evaluation.
