Effect of Lateral Filter-Paper Drains on the Triaxial Shear Characteristics of Soils

Source

Three series of consolidated-undrained triaxial compression tests were performed on sedimented specimens of sodium kaolinite with pore water pressures measured; one series without lateral filter-paper drains and one series each with Whatman No. 1 (weak) and Whatman No. 50 (strong) slotted lateral filterpaper drains. Both total stress and effective stress shearing parameters were determined for both normally consolidated and simply overconsolidated specimens using two failure criteria, the peak stress difference and the point of effective stress path tangency, to determine the effect of the drains on the shearing properties of clays. The tests demonstrated that the drains may either increase or decrease the shearing parameters, depending on the relative strengths of the filter paper and the soil.
