Abstract
It is difficult to identify dispersive clay from non-dispersive clay by the grain graduations, so special devices and testing methods are required. The author probed into the conventional variable head permeability testing method for dispersive clay identification, and concluded that we can preliminarily judge whether the tested clay is dispersive by extending the test time, observing the outlet flow change, analyzing the test data, and checking the sample internal structure after the test is finished.关键词
