Abstract
This paper presents a brief summary of the triaxial single and multi-level loading test technique to model the soils experiencing wind and/or wave kinds of load. Some important findings regarding the shear strength and pore pressure phenomenon in the repeated triaxial experiments are given. The method describing the stress path under single- and multi-level repeated stresses is established in detail. Based on a large number of the test results, some typical stress paths are presented m the effective deviation and normal stress space. The stress paths under single repeated stress at different effective ambient pressures have the same pattern and can be normalized by effective ambient pressure. The pore pressure will increase with the number of repeated stresses and residual deformation accumulated. The stress paths under multi-level repeated stress indicate that the preshearing and consolidation have great effect on the response of effective stress path and make the soil behave as apparently over-consolidated soils. Furthermore, the stress paths reveal that the positive preshearing effect may inhabit the buildup of pore pressure in the soil specimen tested.
