Lw. Morland et R. Staroszczyk, UNIAXIAL WAVE-PROPAGATION AND PORE PRESSURE GENERATION IN FLUID-SATURATED SANDS EXHIBITING IRREVERSIBLE COMPACTION, International journal for numerical and analytical methods in geomechanics, 22(9), 1998, pp. 695-720
The propagation of a plane load-unload pulse through a compacting sand
is analysed and illustrated for both dry sand and liquid saturated sa
nd in undrained conditions. A major feature is the interaction between
the initial loading wave and the faster following unloading wave. Fre
e draining and undrained conditions exhibit distinct qualitative and q
uantitative results, and the pore liquid pressure generation is a sign
ificant physical feature. Illustrations show the effects of different
applied surface pulse shapes. (C) 1998 John Wiley & Sons, Ltd.
