Numerical Analysis of Soft Soil Reinforced with Geogrid Encased Stone Column
The use of geosynthetic encased stone columns for improving very soft soil has been widely recognized both regarding economy and performance. The stone columns are encased to offer lateral confinement against bulging which causes excessive settlement. In this study, the analysis of the embankment, resting on very soft soil reinforced with stone column encased from geogrid is carried out to understand its behavior. In this study a comprehensive numerical analysis is executed to study the consequence of encasement parameters like its length and stiffness on the on time-dependent behavior of the system. The result of the study shows significant improvement regarding settlement reduction and lesser lateral bulging of the column. Moreover, it also shows that encasing the column fully perform better as compared to the partially encased column. Similarly, using stiffness of geogrid beyond 5000 kN/m does not show substantial improvement.
