摘要加拿大阿尔伯塔省中部地区存在大量的上层是细颗粒土壤、下层是粗颗粒土壤的被石油烃(PHC)污染的双层土壤系统。针对这类土壤系统,本文构造出不同与J&E模型的解析公式,以初步估计被石油烃污染的土壤或地下水挥发出的有机气体入侵建筑物的流量。应用ECCLIPSE-2003a软件对该区某污染场进行了数值模拟,以验证该公式。结果表明:在这类双层土壤系统中,该公式是有效的。 There are a number of petroleum hydrocarbon contaminated sites in central Alberta, where the contaminated groundwater is first encountered a few metes deep in the sand layer and a clayey silt and silty clay layer, presented for the first a couple of meters below grade. For this kind of soil systems, we derived an analytical formula which is differ from the J＆E model and can be used to evaluate the intrusion rate of contaminated organic vapors into buildings. We verified the results using the ECLIPSE-2003a, indicating that the formula is valid in this kind of soil system.
