本文介绍了在剑桥大学平衡臂离心机上进行的一项研究计划的结果，以研究污染物在工程填埋场周围土壤中的长期迁移。讨论了通过多孔介质运输危险废物的现象，概述了地质技术离心模型的原理，并提出了关于危险废物运输问题的离心模型及其相应原型之间关系的相关比例律。一个离心试验，模拟二维迁移的一个保守的污染物物种从垃圾填埋场，进行了说明，并从三个这样的测试结果。这些结果进行了比较，从现有的一维运输代码的理论预测。L'article presente les resultats d'un programme de recherches effectuees sur la centrifuge a布拉斯equibre de l'Universite de剑桥pour etudier le transfer.
This Paper presents the results of a research programme conducted on the Cambridge University balanced-arm centrifuge, to study the long term transport of contaminants in the soil surrounding an engineered landfill site. The phenomena which govern the transport of hazardous waste through porous media are discussed, the principles of geo-technical centrifuge modelling are outlined, and relevant scaling laws that govern the relationship between the centrifuge model and its corresponding prototype, with respect to the problem of hazardous-waste transport, are presented. A centrifuge test, simulating two-dimensional migration of a conservative pollutant species from a landfill site, is described, and results from three such tests are presented. These results are compared with theoretical predictions from an existing one-dimensional transport code.
