In this study, a typical spoil derived from Permian-aged sandstones and mudrocks, is subjected to stresses up to 20 MPa, with the corresponding changes in degree of saturation and suction measured. The results show that loose spoil with a water content of around 12% (S_r=25%) will collapse to become saturated under a stress of 7 MPa. In contrast, loose spoil with a higher water content of around 16% will collapse to become saturated under a stress of only 1.5 MPa. From these results, a phenomenon is identified whereby spoil in the seepage and capillary zones at the base of very high spoil piles can collapse to a state of saturation. A discussion is provided on the consequences of this for the matric suction and unsaturated shear strength of these spoil materials, which constitute the foundation layer of the pile.]]> Sat 24 Mar 2018 08:03:29 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:18668 Mon 20 Jul 2015 17:06:17 AEST ]]>
