Determination of Vibro - Compaction Parameters by Making a Test Board in a Port Site in Morocco

Abstract Vibro-compaction is a recent technique for treating soils in the mass, thus improving its mediocre geo mechanical properties. In addition, this treatment makes it possible to minimize risk of liquefaction, closely linked grain size soil be treated. The underlying construction project port Nador Morocco requires improve characteristics and particular given that collision zone, near border between two African-Eurasian plates are seismically active (earthquake city Al Hoceima 2004 Morocco). purpose work test different parameters vibro-compaction (mesh, vibration frequency, height passes, duration compaction) necessary obtain objectives set (relative density ≥ 77 %), through carrying out an embarkation on substitute sands main breakwater Port. situ control tests (CPT) dam, which were carried by substitution sand, made confirm results bench. These stipulate one hand mesh 4.00 m most optimal other relative important parameter liquefaction control.
