摘要

[目的] 为了分析不同基质层厚度的绿化屋面对雨水的调蓄作用。[方法] 通过搭建绿化屋面装置

采用人工降雨模拟器开展试验

在不同基质层厚度和降雨条件下

对绿化屋面的降雨-径流过程、持蓄雨水和减滞洪峰能力进行了研究。[结果] 基质层厚度在一定的范围内时

绿化屋面出水的洪峰过程具有很高的相似性;绿化屋面基质层厚度与降雨持蓄率呈指数函数的关系;洪峰削减率与降雨强度无明显关系

主要由基质层厚度决定。[结论] 绿化屋面能在一定程度上降低雨水的径流峰值

减少总的径流量

延缓产流时间

且随着基质层厚度的增加

绿化屋面对雨水的调蓄能力越好。

Abstract

[Objective] To analyze the capacity of green roofs with different substrate layer thickness to hold rainwater and reduce the runoff.[Methods] A series of green roof assemblies were constructed

and artificial rainfall experiments were carried out. Under the different condition of substrate layer thickness and simulated rainfall intensities

rainfall-runoff process and rainwater retention and reduction capacity were studied.[Results] There is a relationship between runoff processes of green roofs and different substrate layer thickness; The thickness of substrate layer of green roofs has exponent relation with rainwater retention rate; Rainwater reduction rate has no obvious relation to rainfall intensity

and it mainly depend on the substrate layer thickness.[Conclusion] Green roof can reasonably reduce the peak flow

total volume of runoff and delay the runoff generation

and the capacity increased with the increase of substrate layer thickness.
