Abstract: A series of undrained monotonic and cyclic triaxial tests were performed on silica sand at two initial densities and different confining pressures from 0.1 to 5 MPa to investigate their shear response and crushing behaviour. The influence of particle crushing on the undrained shear strength and pore-water pressure was examined. To clarify the evolution of particle crushing, undrained monotonic and cyclic tests were terminated at several distinctive stages and sieving analysis tests were subsequently performed … Show more

“…In the initial stage, particle breakage is very small and it occurs at certain energy, which increases from the beginning of isotropic compression. e result is consistent with the experimental observation by Yu [12], Hyodo et al [18], and DEM result simulated by Liu et al [53]. e data distribution may be fitted well by a hyperbolic equation of the following form:…”

“…Coop et al found that a constant grading can be reached at very large strains on carbonate sands, even quartz sands at low stress levels, were subjected to small amounts of particle breakage [15,16]. Wu et al [17] and Hyodo et al [18] found that the large amount of particle breakage resulting from the high-level strain was induced by particle transformation and rotation during shearing. Yu [12] conducted a great deal of triaxial tests under various influence factors (e.g., confining pressure, initial void ratio, and drainage condition) and discussed the effects of these factors on particle breakage and whole volume change.…”

“…The hydrate crystals can enhance the strength and the stiffness of hydrate-bearing specimens [15][16][17]. The reduction of Ko for the Sh = 0.96 specimen under relatively low vertical stress (σv < 1 MPa) is primarily caused by the cementation between soil particles and hydrate crystals.…”

“…p cr refers to the mean stress when the peak stress ratio reduces to the stress ratio at the critical state. The peak stress ratio η p only emerges for the soil at the dense state [22][23][24]. η p approaches to η cr at the critical state as the mean stress p is increased to be identical to p cr .…”
