Title: Influence of the Rate of Construction on the Response of PVD Improved Soft Ground
Abstract: The major problem of embankment on soft soil foundations is to overcome excessive settlement, initiating undrained failure of the infrastructure, provided proper ground improvement is not planned. One of the most widely used solution to this problem is to stabilize the soft soil foundations under embankment, by the installation of prefabricated vertical drains (PVD), which is carried out throughout the world. It is observed that the installation of vertical drains highly increases the settlement rate, improves pore water pressure dissipation, and decreases the lateral deformation of the soft clay foundation. The paper presents a numerical model to analyze the response of PVD-reinforced soft soil under embankment loading to the rate of embankment construction by finite element modeling. Apart from predicting the dissipation of excess pore water pressure, lateral displacement and the resulting consolidation settlement with time, the stability factors for different rates of embankment construction have been studied. It is observed that higher stability is manifested by the embankment having a slower rate of construction.
