摘要
通过双环注水试验、常水头钻孔注水试验及室内垂直渗透试验方法对同一土层的渗透系数进行了测定,并对试验结果进行了比较分析,最后指出了双环注水试验的特点及适用范围。
According to the double annulus water injection test method,constant head water injection test method and indoor vertical permeability test method,it carries out the measurement to the permeability of the same soil layer,and carries out the comparison analysis to the test results,in the end,there indicates the features and application range of the double annulus water injection test.
