An experimental program was conducted to investigate the parameters affecting the creep behaviour. One-dimensional single stage, stepwise and overloaded-unloaded compression creep tests were conducted using standard oedometer apparatus on kaolinite and bentonite clay samples. Single and radial drainage conditions with different pore fluids were considered. Required creep stress levels were achieved using instantaneous loading increments. Effects of stress level, stress history, pore fluid chemistry, fabric structure, drainage condition and mineral compositions of clay on creep behaviour were studied based on the experimental results. Drainage condition exhibited insignificant influence on creep. Creep mechanisms were explained as a combined effect of sliding of clay particles at their contacts and deformation of particle itself. Compression of micro pores during the creep is negligible. Developed model successfully describes the creep behaviour interims of viscosity.xvi, 137 leaves : ill. ; 30 cm.engUniversity of Calgary graduate students retain copyright ownership and moral rights for their thesis.
