摘　　要：近年来,直接推进技术以其快速精确、经济高效、可装备先进探测器等优点,在国外污染场地调查中得到广泛推广与应用。文章在总结国内外相关研究成果基础上,对直接推进技术中的膜界面探测和连续钻进取样技术在污染场地调查中的功能和应用进行了论述,并在某有机污染场地调查中进行了试验研究。结果表明,利用膜界面探测技术首先半定量获取场地污染物的分布特征及范围,然后以此为指导采用直推式钻机钻进获取代表性样品,并进行实验室测试分析,可以快速、精确地刻画有机污染场地的污染物种类、浓度与分布范围,为后期采样计划和调查提供重要依据。Direct push technology has been extensively used in investigation of contaminated sites in developed countries. It is of advantages,such as direct sampling,accuracy,low cost and high efficiency. Moreover,it can carry advanced detectors on its probe favoring additional measurements. This paper summarizes the international researches of the direct push technology, discusses its functions and application to the contaminated site investigation,and introduces the application of membrane interface probe and continuous sampling technology in a contaminated site with organic pollutants. The membrane interface probe is first used to get the characteristics of contamination distribution and extent,and continuous sampling is carried out to obtain representative samples for laboratory tests. This procedure is certified to be fast and accurate for the investigation of organic contaminated soil and groundwater,and can provide important basic information for the followed investigations.
