Abstract
This paper presents the study of the rupture of an embankment on soft clay, localized in Recife, Brazil. The data was obtained from partnership of the Department of Civil Engineering of the Federal University of Pernambuco, Brazil and the company Gusmão Engineers Associates, which it was possible to perform a Master Thesis. The embankment was constructed without geotechnical investigation project, accompaniment and technological control. After the rupture, to understand the process, a geotechnical investigation was performed to permit a total stress stability analyze / back-analyze, considering circular and non-circular surfaces, occurrence of cracking in embankment, and the three-dimensional effect. The Data Base of Recife soft clays (Coutinho et al. 1998c) were used to complement the technical information necessary to the study. In the evaluation of the undrained shear strength of the foundation (Su) was used the results of field vane test, with consideration of the corrections proposals for Bjerrum (1973). All the results of this work showed that rupture was previsible if adequate geotechnical investigation and stability analysis had been done.
