摘要 在地下水环境影响评价工作开展过程中,为判断项目所在地包气带的防污性能,工作人员通常采用双环渗水试验来获得较为准确的包气带渗透系数。本文在天津某化工项目地下水环评双环渗水试验的实际应用中,通过搜集资料、现场操作和室内分析,为该项目获得包气带防污性能,确定项目区地下水环境保护防渗分区措施,给出了准确可靠的技术参数。这对地下水环境影响评价工作具有很好的实际意义,也为典型化工项目地下水污染分区防控提供了工程实例。 In the process of groundwater environmental impact assessment,in order to judge the anti-fouling performance of the vadose zone in the project site,the staff usually use double-ring seepage test to obtain more accurate permeability coefficient of the vadose zone.In this paper,through collecting data,field operation and indoor analysis,the anti-fouling performance of vadose zone is obtained for a chemical project in Tianjin,and the anti-seepage zoning measures of groundwater environmental protection in the project area are determined,and accurate and reliable technical parameters are given.This is of great practical significance to the environmental impact assessment of groundwater,and also provides an engineering example for the prevention and control of groundwater pollution zoning in typical chemical projects.
