A large-scale trial embankment provided with partially penetrating prefabricated vertical drains (PVD) was installed in consolidating marine clay deposits at East-Port said industrial zone project in Egypt. The trial embankment was constructed with a bottom area of 150x150m and a height of 5.5m to evaluate the efficiency of the improvement system and verify the design parameters. An intensive instrumentation system was built-up including shallow settlement indicators, vibrating wire piezometers, extensometer, and inclinometers. Two and three-dimensional finite element analyses (FE) were performed to study the effect of the preloading system provided with partially PVD in consolidating marine clay deposits. FE models were validated and showed good agreement with the field observations in terms of vertical displacement of embankment center, and lateral soil deformation beneath the embankment toe.

The full scale trail embankments were constructed to a height of 3.65m over the soft marine clay at Juru, Butterworth,Pulau Pinang. One of the embankments was improved using prefabricated vertical drains (PVD),and the other one without treatment was control embankments. Monitoring instruments such as hydrostatic  profile gauges, settlement gauges ,inclino,eters and piezometers were installed in the subsoil to observe the deformation behavior of the embankments under loadings.
