【摘要】 为了研究降雪过程对海绵城市典型LID设施的影响,通过对典型LID设施融雪适应性分析,结合降雪及融雪过程的具体理论,建立典型LID设施融雪SWMM模型的研究方法。并且通过理论分析发现,与降雨期不同的是,在利用SWMM模拟软件进行降雪期模拟时,不仅需要足够的降水数据和具体的LID设施参数,还需要温度、风速、积雪的蒸发速率、海拔高度、积雪的相关参数以及对各区域积雪处理方式的选择等参数的输入,并确定模拟所使用的渗透模型为霍顿模型。更多还原

【Abstract】 In order to study the influence of snowfall on the typical LID facilities of sponge city,through the analysis of the snowmelt adaptability of typical LID facilities,combined with the specific theory of snowfall and snowmelt process,a research method of snowfall and snowmelt simulation with SWMM simulation software was found.And through theoretical analysis,it is found that,unlike the rainfall period,when using the SWMM simulation software for snowfall simulation,not only sufficient precipitation data and specific LID facility parameters,but also temperature,wind speed,evaporation rate of snow,and altitude are required.Inputs of parameters such as height,snow-related parameters,and selection of snow processing methods in each area,and determining the permeation model used for the simulation as the Holden model.更多还原
