摘要
以西安一小区居民楼为研究对象,构建了高精度城市雨洪模型,并通过实测暴雨内涝监测数据验证了模型的可靠性;利用构建的模型模拟了6种设计降雨重现期下的居民楼室内动态淹没过程,并以西安市中等收入家庭的房屋配置为计算单元,分析了各类居民室内财产的淹没水深阈值,依此拟合得到了室内财产淹没水深-损失率关系曲线,结合居民楼在不同降雨重现期下的淹没水深,计算得到了各居民楼在不同降雨重现期下的内涝淹没财产损失数据。结果表明:不同降雨重现期下,同一居民楼一层居民房屋室内进水淹没水深随降雨重现期的增大而增大;同一降雨重现期下,各栋居民楼因高程不一致导致内涝淹没过程及最大淹没水深不一样。
Taking the residential buildings within a small community in Xi’an as the study object,a high-precision urban rain-flood model was constructed.The model’s reliability was validated using measured data from monitoring instances of urban inundation during heavy rainfall.The dynamic flooding process inside the residential buildings under six different major rainfall return period design scenarios was simulated.Considering the housing configuration of middle-income families in Xi’an City as the computational unit,the depth thresholds for the flooding of various indoor properties were analyzed,and the relationship curve between the depth of indoor property flooding and the corresponding loss rate was derived.By combining this curve with the flooding depths of different residential buildings in the study area under various major rainfall return periods,accurate data on property losses due to flooding were obtained.The results indicate that under different rainfall recurrence intervals,the inundation depth of the ground floor of the same residential building increases with the larger recurrence interval.For the same recurrence interval,the flooding process and maximum inundation depth of houses in different residential buildings vary due to differences in elevation.
