Abstract
Rigid Inclusion System (RIS) is one of the economic systems for improving highly compressible soil by increasing the bearing capacity of foundation soil and reducing settlements. This system consists of a load transform platform (LTP) with or without geosynthetic reinforcement (GR) membrane resting on an arrangement of piles. The LTP redistributes the fill embankment load so that a higher percentage of load is transferred to pile by arching that leads to a reduction in the settlement of the foundation soil. Many analytical, numerical and experimental studies to model arching within LTP using cohesionless fill are summarized. This paper presents an analytical model to explain the arching behavior within LTP using cohesive fill instead of cohesionless fill. The analytical model is verified by comparison with field measurements from a case history. Furthermore, the results of the analytical model are compared with a numerical model using PLAXIS 3D.V20. The results show that the use of cohesive fill in the LTP improves arching within the LTP.
