| Piled raft is known to be an unfavorable foundation type in soft clay because foundation is associated with both excessive settlement and bearing capacity failure problems. Despite these reasons, in recent decades, an increasing number of structures have been constructed over soft clay area, piled raft concepts arouse interest as the foundation of structures on soft clay area becomes popular. This study described 3 dimensional behavior of piled raft on soft clay based on a numerical study using 3D finite element method. A series of numerical analyses were performed for a various pile lengths and the pile configurations on the raft were subjected to vertical uniform or point loading. Based on the results of the parametric study, comparisons were made among the effect of loading type, various pile length and configurations, and the load-settlement behavior and load sharing characteristics of piled raft were also evaluated. From the results, the characteristic of piled raft on soft clay was examined. |
