Abstract

This paper investigates the feasibility of using air trapped in the pores of soil to reduce soil permeability and hence form a barrier to groundwater flow. The laboratory experiments carried out investigated: (a) how to inject air into the soil in such a way that contaminated water is discouraged from entering the air-injected (sparged) region; (b) what factors affect the airflow; and (c) whether the sparged region can deflect a plume of contaminant. It was found that this application of air sparging can be used to form a barrier to groundwater flow in laboratory scale experiments.

空气喷射控制地下水污染的实验研究

本文探讨了利用土壤孔隙中的空气来降低土壤渗透性，从而形成地下水流动屏障的可行性。所进行的实验室实验研究:(a)如何向土壤中注入空气，使受污染的水不能进入注入(喷射)空气的区域;(b)影响气流的因素;(三)喷溅的区域是否能使污染物的羽流偏转。在实验室规模的实验中发现，空气喷射的这种应用可以用来形成地下水流动的屏障。

期刊介绍： The objectives of the Association shall be the promotion of co-operation among geotechnical societies in SE Asia; and the assistance to member societies who have limited number of members. Now there is only one combined web titled: AGSSEA-SEAGS. SEAGS & AGSSEA encourage the submission of scholarly and practice-oriented articles to its journal. The journal is published quarterly. Both sponsors of the journal, the Southeast Asian Geotechnical Society and the Association of Geotechnical Societies in Southeast Asia, promote the ideals and goals of the International Society of Soil Mechanics and Geotechhnical Engineering in fostering communications, developing insights and enabling the advancement of the geotechnical engineering discipline.
