An Investigation Of Monotonic And Cyclic Behaviour Of Leda Clay, Kimberly K. Rasmussen
Electronic Thesis and Dissertation Repository
The behaviour of a sensitive clay from Ottawa is investigated though strain- and stress-controlled cyclic simple shear, and resonant column tests. Strain-controlled tests were performed at frequencies 0.1 to 10Hz, and amplitudes 0.1% to 5%. Over this range of strain amplitudes there are large drops in stiffness. Strain amplitude has a greater effect on the generation of pore-pressures than frequency. Stress-controlled tests performed at a yield stress ratio of 1 had higher strength at low N but degraded more readily than a test at YSR =2. A novel method of remoulding clay and measuring the remoulding energy is also presented. …
