摘要
针对山丘区串(并)联水库群溃坝后的风险问题,选取泰安市果庄河流域内的4座小型串(并)联水库为研究对象.采用数值模拟的方法对串(并)联水库群的溃坝淹没情况及风险性进行了分析,计算了水库溃坝流量,搭建了二维水动力学模型进行水库溃坝数值模拟.通过分析不同溃坝方案下小型梯级水库群淹没要素,以淹没面积为风险评估指标进行风险性分析,分析结果可为山丘区串(并)联水库的溃坝风险评估和风险对应提供技术支撑.
Abstract
In view of the dam break risk of parallel and serial-connected reservoir group in hilly area,4 small reservoirs in Guozhuang River basin of Tai'an Municipality were selected as the research objects.The flood situation and risk were analyzed by numerical simulation method,and the dam break flow rate of the reservoir was calculated,and a two-di-mensional hydrodynamic model was built for numerical simulation of dam break of the reservoir.By analyzing the inun-dation factors of small cascade reservoirs under different dam break schemes,the inundation area is taken as the risk as-sessment index to carry out risk analysis.The analysis results can provide technical support for dam break risk assess-ment and risk response of cascade reservoirs in hilly areas.
