摘要：

Undrained triaxial tests performed on sandstone specimens with two different porosities showed that the observed induced pore-water pressure response is quicker in high porous sandstone and the maximum observed induced pore-water pressure is higher compared to that of low porous sandstone. Volumetric strain results showed that the dilation is a significant mechanism only at low confining pressures for both types of sandstone. Within the tested confining pressure range, a considerable difference in the onset of dilatancy relative to the peak differential axial stress was not observed.
