Vertical and Horizontal Laboratory Permeability Measurements in Clay Soils

摘要: Publisher Summary This chapter discusses the vertical and horizontal laboratory permeability measurements in clay soils. The direct measurement of k v permeability, h , soils validity Darcy's law materials may be considerable importance estimating pore water pressure dissipation, settlement rates, few with this as specific purpose have been made. enable a better estimate field consolidation behavior to made either marked creep properties or more pervious macro structure. first effect is clearly demonstrated by tests on one undisturbed three remolded clays. Tests demonstrate second point are, at present, being was generally valid, exception occurring organic where permeant not chemical equilibrium fluid changing under constant hydraulic gradient occurred, possibly result particle migration. new permeameter systems functioned well throughout tests. A possible difficulty interpretation radial flow test results because smearing drains. It can solved measuring seepage distribution across sample base.
