Web19 Jan 2016 · In either case, the usual treatment of porosity by rock compressibility must be replaced by the coupling with stress-strain solution. The porosity changes become more complex when failure of the skeleton is reached either in compression (rock compaction) or in shear. Flow-properties coupling WebFirst, a vibroflot is driven down into the ground with a device to create a hole. Granular material is then inserted into the device and compacted to create a column in the ground. The compactive device then slowly lifts, and the column continues to be built in lifts as the flot is extracted.
