This paper presents the results of an elastoplastic finite element back analysis of an excavation made on a saturated soft organic clay deposit in Rio de Janeiro, Brazil. The excavation was conducted as part of an urbanization program, in which artificial ...

A coupled hydromechanic analysis predicts a significant pore pressure drop due to the volumetric expansion associated with the excavation of the pit. This lower pore pressure distribution allows for a more aggressive and economical slope design.
