Assessment of Shear Failure Parameters for Sand-Clay Liners
The cohesion and angle of internal friction are generally the key parameters required in the analysis of different geotechnical problems. Variably, expansive soils undergo volume changes when subjected to moisture increase. Accordingly, the attraction forces between the clay particles and the internal friction are deemed to vary for different soil fabrics and different states of stresses. The influence of moisture on the shear strength parameters of clay liners need to be established to achieve adequate design. In this study, undrained direct shear tests were carried out for Al-Qatif clay sand mixtures at variable moisture contents in order to assess the variation of shear strength parameters when sand clay liners are inundated. The mold placement density was maintained the same for all moistures tested. The influence of moisture change on the shear strength parameters was assessed for the material used. In order to forecast the moisture profile in a clay liner, hydraulic conductivity as well as water retention properties was investigated.
