The compaction of loose watersaturated soil deposits by means of falling weights or explosions has been applied since many years on a purely empirical basis. A theoretical description of this phenomenon of segregation and migration of porewater is missing to date although the pore pressure generation in the course of undrained contractant shearing is well understood. There is still a need for an explanation of the compaction, which occurs subsequently to undrained shearing and the corresponding pore pressure generation. In this paper an alternative mechanism of soil consolidation is considered which is completely different from the one introduced by Terzaghi, in that it is based (i) on discontinuous motion, and (ii) on phase transition. The phenomena considered here are similar to the ones related with the migration of magma in the earth crust, where the magma plays the role of the porewater. [ABSTRACT FROM AUTHOR] |
