The long-term experiment E5/0,2 with pressure at rest and passive pressure of ideally non-cohesive sand ran in 2010 and consist of a number of phases which brought huge quantity of data. The experiment contained also a phase of consolidation after passive wall rotation about the top with a toe movement of 15.6 mm. Movement velocity of the front wall toe was 0.005 mm/min. only. On the contrary, processes of the pressure components (normal and shear) were surprisingly quick. The Paper presents an analysis of a process of time pressure instability at the beginning and the end of a reconsolidation phase.
