摘　　要：在Geiger定义的基础上,通过简易测定雨强,引入综合污染负荷,建立了高速公路路面径流初期效应大小、方向、时段的数量化判定方法。以G75兰海高速重庆段为例,研究了2009-04-30、2009-06-09、2009-08-29等3场降雨事件的初期效应,发现2009-04-30降雨有明显的初期效应,2009-06-09降雨则没有,2009-08-29降雨则处于临界状态,2009-04-30、2009-08-29这2场降雨的初期效应分别为68.11%和50.48%,其相应的初期效应时段分别为15 min和25 min。The quantity method for determining the first flush effect of expressway surface runoff properties such as amount, direction and period of time was established by simply measuring rain strength and calculating pollution load based on Geiger＇ definition about the first flush effect. The method developed in this paper was used to investigate the first flush effect of rainfall in April 30, June 9 and August 29, 2009 in the Chongqing section of G75 Lanzhou-Chongqing expressway. It is found that （ 1 ） the first flush effect of rain event in April 30, 2009 was occurred remarkably, while the effect was not occurred in June 9, 2009, and the effect in August 29,2009 was in critical state; （2） the first flush effect of rain events in April 30 and August 29, 2009 are 68.11% and 50.48% respectively, and their period of time are 15 rain and 25 min respectively.
