SETTLEMENT PREDICTION OF PVD-IMPROVED GROUND WITH TIME DEPENDENT WELL RESISTANCE

Abstract

This paper presents a new settlement prediction method of PVD-improved soft soil ground, in which the equation of settlement prediction method is proposed based on the time dependent well resistance. Based on an analytical solution, a time factor-well resistance relationship is established. This relationship is then verified through large sample consolidation test. The new method for settlement prediction is proposed based on the time factor-well resistance relationship. The proposed method is applied to a test embankment. The proposed method provided a good agreement with field data. It is suggested that the proposed method in this study can be used to predict settlement of PVD-improved ground under embankment.
