摘要
利用GIS软件MapInfo对文峪河水库下游文水县的一些基础资料进行分析处理,利用内插法生成洪水淹没区等高线图和实体地形图等。利用损失率计算模型对淹没区内损失状况进行了预评估。结果表明,当文峪河水库遭受重现期为5000年一遇的洪水时,会发生漫顶溃坝,洪灾所造成的直接经济损失约为24.149亿元,间接经济损失约为4.347亿元。通过对水库溃坝洪水淹没损失的计算分析,可以让防洪决策人员及水库管理人员对发生水库溃坝洪水可能产生的后果做到心中有数,防止灾害发生。
Contour and topographical map of flood areas in the lower reaches of Wenyuhe Reservoir was generated by using MapInfo （GIS software） to process basic data of Wenshui County and using interpolation method.The model for the loss rate was used to assess the loss status of the inundated area.When the reservoir met the flood of a return period of 5000 years,the overtopping dam-break incident could occur and the flood could cause the direct economic loss to 2.4149 109 RMB and indirect economic loss to 4.347 108 RMB.Calculation and analysis of the loss by dam-break flood in this paper will enable policy makers and reservoir supervisors to know the consequences of the floods so as to avoid the disaster.
