Abstract
The purpose of this study is proposing for the test method for measuring the hydraulic conductivity of bentonite mixtured soil used as a seal liner of waste disposal site after the construction in situ. Concretely, it is a method for building in the moisture sensor in which the measurement in the pinpoint was possible for Air Entry Permeameter, which exists in situ permeability test method. In results of this study, by catching fall time of wetting front, 10-8(m/s) order of hydraulic conductivity could be measured in about 10 minutes. And, the validity of this proposed method was verified by carrying out the one-dimensional infiltrating test, and measuring moisture profile and pressure distribution in the test-piece.
