摘要:
针对溃坝洪灾避难场所选址中对潜在淹没区域危险程度重视不足的问题,提出了一种新的溃坝洪灾避难场所选址评价模型。 首先,在构建危险度评价指标体系的基础上,运用改进突变评价法对潜在淹没区域进行危险度评价和危险等级划分;其次,将避难场所与高级别危险区的距离作为选址评价指标,并考虑避难场所的灾害风险、位置规模、应急保障等条件,通过层次分析法确定权重,运用 TOPSIS 法对避难场所进行选址评价;最后,以我国陆浑水库下游 13 个潜在淹没区域和 10 个备选避难场所为例进行验证。 结果表明:危险等级较高的潜在淹没区域中,白元镇为Ⅰ级危险区,彭婆镇、鸣皋镇、城关街道、龙门镇为Ⅱ级危险区,评价较优的备选避难场所能够满足重视高危险度潜在淹没区域的要求。
Abstract:
In response to the problem of insufficient attention to the risk degree of potential inundation areas in thesiting of shelters for dam failure floods, a new model for evaluating the sites of shelters was proposed. On the basisof establishing the risk evaluation index system, the improved catastrophe theory evaluation method was used to evaluate the risk degree and classify the risk level of the potential inundation areas. The distance between sheltersand high-risk level areas was taken as the site selection evaluation index, and the disaster risk, location scale, emergency support of shelters were considered. The weights were determined by AHP method, and the TOPSISmethod was applied to evaluate the sites of shelters. Finally, 13 potential inundation areas and 10 alternative shelters downstream of Luhun Reservoir in China were used as examples for validation. The results showed that amongthe areas with high risk levels, Baiyuan Township was a Class Ⅰ hazardous area, and Pengpo Township, MinggaoTownship, Chengguan Street, and Longmen Township were Class Ⅱ hazardous areas. The better evaluated shelterscould meet the requirements of paying attention to areas with high risk degree.
