REVIEW OF FULL FLOW PENETRATION TESTING IN OCEAN GEOTECHNICAL ENGINEERING PRACTICE

The seabed covered with deep soft soil and it bearing capacity is very low, the traditional CPTU cannot adapt, so we began study the Full Flow Penetration Probe. Full flow penetration test consider the characteristics of soft soil, changed the shape of the probe, and 10 times bigger projected area can accessing and collecting the basic parameters of the test, for the dividing and calculate the basic physical and mechanical indexes of the soil layer very accurately. It's very useful to the geological engineering. This paper conclude the full flow penetration test types, methods, mechanism of penetration and estimate parameter, analysis the advantages and disadvantages of full flow penetration test and the scope of application, Finally prospects the development direction of future full flow penetration test.
