摘要
探明溃坝发生过程,准确预测洪水淹没范围,分析溃坝后果,对水库防灾减灾和应急抢险工作具有重要意义。为此,以深圳市小型水库头陂水库为研究对象,采用经验公式估算入库洪水和最终溃口参数,基于改进的DAMBRK原理和二维模型计算溃坝下泄流量和洪水演进过程,调查淹没范围内受灾人口并制定转移方案。系统性地计算了典型城市地区小型水库头陂水库的溃坝全过程,可为我国缺少监测资料的小型水库溃坝计算提供理论参考。
It is of great significance to explore the process of dam break,accurately predict the scope of flood inundation and analyze the consequences of dam break for reservoir disaster prevention and mitigation and emergency rescue.To this end,the Toupei Reservoir,a small reservoir in Shenzhen,is taken as the research object,and the parameters of inflow flood and final breach are estimated by empirical formula.Based on the improved DAMBRK principle and two-dimensional model,the discharge of dam break and flood routing process are calculated,and the affected population in the inundated area is investigated and the transfer scheme is formulated.The whole process of dam break of Toupi Reservoir in typical urban area is systematically calculated,which can provide theoretical reference for the calculation of dam break of small reservoirs without monitoring data in China.
