【摘要】：通过对湖北省武湖和涨渡湖分蓄洪区洪水风险图编制工作的总结,介绍了这2个分蓄洪区洪水风险图编制的范围、内容及方法,探讨了溃口洪水风险的影响因素,并分析了分蓄洪区特征参数可能存在的问题。结果表明此次复核的武湖分蓄洪区的容积和面积与《长江流域防洪规划》中的值基本一致,但涨渡湖的值却差别很大。另外,根据编制成果,无论长江干流扒口还是支流溃堤,武湖分蓄洪区的三里桥街和武湖街,涨渡湖分蓄洪区的双柳街、涨渡湖街和汪集街等地势低洼地区,洪水到达较快,受影响均较严重。但由于安全设施缺乏,安全避洪转移存在着一定困难,因此对避洪转移方案提出了新的思路,建议利用分蓄洪区内的高速公路进行人口的转移和临时安置。研究成果可为后续分蓄洪区的风险图编制提供参考。
[Abstract]:Based on the summary of the compilation of flood risk maps in the flood diversion and storage areas of Wuhu Lake and Xiangdu Lake in Hubei Province, this paper introduces the scope, contents and methods of the flood risk maps of these two flood diversion and storage areas, and probes into the influencing factors of flood risk at the breakout. The results show that the volume and area of the flood diversion and storage area are basically the same as those in the "Yangtze River Basin Flood Control Planning", but the value of the lake is very different. According to the results of the compilation, no matter whether the Yangtze River branches break the embankment, Sanliqiao Street and Wuhu Street, Shuangliu Street, Shandu Lake Street and Wangji Street in the Wuku Flood diversion and Storage area, the flood reaches relatively fast in low-lying areas, such as Shandu Lake Street and Wangji Street. However, due to the lack of safety facilities, there are some difficulties in the transfer of safe flood avoidance, so a new way of thinking is put forward for the scheme of flood avoidance transfer. It is suggested that the freeway in the flood diversion and storage area should be used for population transfer and temporary resettlement. The research results can be used as a reference for drawing up the risk map of the flood diversion and storage area.
