Modelling of rigid inclusions reinforced foundations to investigate the failure envelope in the V-M-H space
Résumé
The technique of ground reinforcement using Rigid Inclusions (RIs) is known to reduce settlements and enhance bearing capacity in soft soils. This approach leads to significant nonlinear interactions among the load transfer platform, piles, and the surrounding soil. The main objective of this paper is to identify the failure envelope of a shallow foundation on soft soil reinforced by RIs. This is a critical step in the safety assessment of this combined foundation system under static and dynamic (seismic) loading. The failure envelope, defined in the vertical force (V), bending moment (M) and horizontal force (H) space, is constructed using swipe tests from numerical simulations. A simple analytical formula is proposed to describe the failure envelope in V-M-H space. The failure envelope described by the proposed equation is the key ingredient for the macro-element modeling for the analysis of Soil-Structure Interaction of RIs foundation systems.
