摘要
为研究汇水区面积与生物滞留池表面积比值、生物滞留池结构、降雨强度、降雨历时以及汇流类型等因素对生物滞留池水文效应的影响,设计了一种模拟自然降雨条件下生物滞留池运行效能的试验装置,以克服传统埋地式试验装置仅能依靠天然降雨进行试验及直接喷淋式地上试验装置模拟的降雨径流过程线与实际情况存在较大差异等缺点。分析模拟自然降雨条件下生物滞留池运行效能试验装置的构造及试验原理,并讨论该装置实际应用的可行性。
In order to study the influence of different factors on the hydrological effect of the bioretention pond,including the ratio of the area of the catchment area to the area of the bioretention pool,the structure of the bioretention pool,the rainfall intensity,the duration of the rainfall and the type of confluence,a test device for the performance of the bioretention pond under the simulated natural rainfall conditions was designed in order to overcome the disadvantages of that the traditional buried test device can only be used under the natural rainfall events for testing and that the rainfall runoff process line simulated by the direct spray ground test device is quite different from the actual situation.This paper analyzed the structure and test principle of the performance test device for simulating the bioretention pond under natural rainfall conditions,and discusses the feasibility of the practical application of the device.
