摘要：
The effect of a “pore-size” length-scale parameterl on compaction of grounds with fluid inclusions is studied. They are modelled as continua endowed with micro-structure by means of the macro-modelling procedure proposed in [2]. We show the dependence of field evolution equations on the micro-structure parameterl and compare our model with the homogenized asymptotic ones. The consideration of the pore sizel allows us to forecast the onset ofmicro-displacement waves as a consequence of a ground settling and to suggest a possible description of the genesis of certain microerthquakes [5] [6].
