摘　　要：通过试验,对极端降雨条件下透水水泥混凝土路面在削减洪峰流量、径流总量以及去除污染物的效果进行研究。试验表明,在降雨历时60 min,降雨量为110,135,163 mm的情况下,透水水泥混凝土路面削减径流总量为55%~69%,削减洪峰流量为55%~63%;对SS、COD、TN、TP的去除率分别为82%~95%、58%~78%、31%~74%、59%~80%。结果表明,在极端降雨情况下,透水水泥混凝土路面在削流除污方面的效果较好,且与一般降雨条件下的除污效果相近,因此在暴雨情况下,也可产生较好的环境效益,表明其具有气候普适性,是一种良好的海绵城市建设技术。Under the condition of extreme rainfall,reduction effect of rainfall and runoff and removal efficiency of pollutants conducted by the pervious concrete pavement were studied. The results showed that when the duration of rainfall was 60 min with rainfall of 110,135 and 163 mm,the pervious concrete pavement could reduce 55% ～ 69% of the runoff and 55% ～63% of the rainfall,and removed 82% ～ 95%,58% ～ 78%,31% ～ 74% and 59% ～ 80% of SS,COD,TN and TP,respectively. We found that the effect of rainfall reduction and runoff pollutants removal by pervious concrete pavement was better under the condition of extreme rainfall,which was similar range compared with the condition of general rainfall. The pervious concrete pavement gives better benefits for environment,and has climate adaptability,and can be a good technology for sponge urban construction.
