摘要
为了解南水北调中线一期工程总干渠试验段膨胀岩的基本特性,开展了膨胀岩的现场渗透试验。对比分析采用Guelph渗透仪和双套环对黏土岩和泥灰岩测得渗透系数。结果表明,泥灰岩渗透系数范围在10^(-4)～10^(-6)cm/s之间,黏土岩渗透系数范围在10^(-5)～10^(-6)cm/s之间,测试结果基本反映了岩体渗透性能。
In order to reveal the fundamental characteristics of swelling rock along the Middle Route of South-to- North Water Transfer Project, in-situ tests were performed. The permeability coefficient tests for marl and clay rock adopted the Guelph Permeameter and Double-Ring. The test result is compared. It is concluded that the range of permeability coefficient of the clay rock is between 10^-4 cm/s and 10^-6 cm/s, and that of the marl is between 10^-5 cm/s and 10^-6 cm/s. The test results are reasonable.
